Successfully treated a planted invert tank!
API Super Ick Cure Tank Details: -10 gallon, heavily planted -Driftwood with current biofilm -78ยฐF usually -6.5 pH, slowly increasing with blanched cuttlebone -0 ppm Nitrite & Nitrate <0.25 ppm Ammonia -Relatively low GH & KH; working on establishing a bit higher levels 1x Crowntail Male Betta 2x Shrimp 1x Mini Mexican Lobster 2x Nerite Snails 1x Chinese Striped Butterfly Loach 1x Golden Siamese Algae Eater Stocking is not ideal; however an acquaintance of mine needed to get rid of the algae eater & loach asap so I was working with what I had. Mid-process of cycling to upgrade to a 40 gallon breeder. Fluval filter is rated for 30 gallons and my water parameters have always been excellent. No bio-spikes, no tank aggression, everyone gets a frozen or blanched diet. Was unable to sufficiently quarantine the loach or algae eater (completely my fault and inability) so thatโs how we ended up hereโฆ Onto the Ich! Everyone has been okay for about a week; then two days ago (as of May 12th, 2026) I noticed a singular white spot on my betta (Sukuna). Genuinely thought it was a color shift or mutation since he is still a juvenile. Nope; more spots appeared within the two days. Immediate yikes, and I knew I had messed up horrifically with โsavingโ those two bottom-feeders. Immediately ordered API Super Ick Cure. Itโs important to note that no other fish had shown signs of ick. No spots, no lethargy or rubbing, etc. Sukuna did not display any behavioral changes; no real rubbing or scratching, no lethargy, no loss in appetite. Maybe had his fins a bit more narrow. However I was confident this was ick and not something else. Going into this; I knew there was a massive risk of treating given the invertebrates present. I was unable to set up a quarantine tank, so we had to go risky and treat the whole tank. It should be noted this is not recommended as the copper in ick treatments can harm / kill invertebrates and loaches, etc. Before treating, I did a 30% water change. Tested water beforehand, parameters were perfect as usual. Used water conditioner plus stress coat on replacement water. Day Zero, 5/12: Removed activated charcoal portion of filter media. Treated with 5ml despite having a 10 gallon; I wanted to try and salvage the invertebrates and loach if possible. I also gradually began to increase the temperature from 78ยฐ to 84ยฐ, over a period of 18 hours. Cranked up my airstone output and filter aeration as warm water doesnโt hold as much dissolved O2. Tentatively hopeful, everyone seemed okay. Day One, 5/13: Everyone still alive & active. Sukuna does seem to be flashing / rubbing on things now, but he does seem to have less white spots attached. Did a 20% water change, treated new water with conditioner + stress coat. Treated with 5 mL of Super Ick Cure. Temp up to 86ยฐ this seemed to get the rest of the white spots off so they could hatch & become vulnerable to treatment. Day Two, 5/14: Everyone great again this morning. Both shrimps still alive, one even molted. Everyone still active, inverts still eating (fed after water change, before adding treated water). Increased water aeration and air stone has resulted in a small fin tear, but other than that Sukuna is extremely active, very engaged and eating great. No more white spots. 20% water change, 5 ml Ick treatment. Temp at 84-86ยฐ. Days Three, 5/15: Sukuna seemed a littler lethargic / breathing fast today, but still ate and swam some. Made sure to adjust airstone to get more O2. Dosed at 5 mL but did not do water change. Day Four, 5/16: Sukuna was much more active and engaging today. Ate his food. Everyone is still alive. Did not change water, and did not medicate. Day Five, 5/17: Everyone is active and alive still. Did not change water, but did medicate again with 5 mL. Added stress-coat to the water, about 5 mL. Day Six, 5/18: Everyone still good! Did a 20% water change. Did not medicate water, but added stress coat. Day Seven, 5/19: Everyone alive and well. Considering this my last day of treatment, but I will kept the aquarium temp up to 84ยฐ for the next few days. Will treat with 5 mL today, change water tomorrow, and call my tank Ich free!

A Must-Have for Any Aquarist โ API Liquid Super Ick Cure!
I recently used the API Liquid Super Ick Cure for my aquarium, and I have to say, it's a lifesaver! Here's why I'm giving it a 5-star review: 1. Fast-Acting Treatment: This liquid medication is incredibly effective in treating Ich (White Spot Disease), which can be a nightmare for aquarium owners. I noticed a significant improvement in just a couple of days after starting treatment. My fish looked much better, and the white spots on their skin began to disappear. It's definitely a quick and reliable solution! 2. Works for Both Freshwater and Saltwater Fish: I love how versatile this product is. Whether you have a freshwater tank or a saltwater aquarium, this medication works for both types of fish. This is a huge plus because I have a mixed tank, and I didnโt need to worry about using separate products for different species. Itโs a one-stop treatment! 3. Easy to Use: The API Liquid Super Ick Cure is very straightforward to use. The dosing instructions are clear and easy to follow, making the whole process less stressful. The liquid form makes it easy to add directly to the tank without any mess. I just followed the recommended dosage, and it worked wonders. 4. Safe for Fish: What I appreciate most is that this medication is safe for my fish when used as directed. I didnโt see any signs of distress or negative side effects in my fish, which is always a concern when treating a sick tank. They were able to continue swimming and eating while undergoing treatment. 5. Affordable and Effective: Considering how much Iโve spent on other fish medications that didnโt work, this product was a great value for the price. You get 4 fl oz in a single bottle, which lasts quite a long time, especially for smaller tanks. The results speak for themselves โ effective treatment at an affordable price. 6. Keeps the Tank Safe: I was initially worried about using medication in my tank because of the potential harm to plants or beneficial bacteria, but this treatment is safe for use with plants and biological filters. It didnโt seem to affect the tank's overall health, which is a huge relief. 7. Peace of Mind for Fish Owners: As a fish owner, itโs always stressful when diseases strike, but having a reliable treatment like the API Liquid Super Ick Cure gives me peace of mind. I know I can trust this product to handle Ich outbreaks effectively and efficiently. Final Thoughts: The API Liquid Super Ick Cure is an essential product for any aquarium owner dealing with Ich. Itโs effective, safe, and easy to use, with fast results. If your fish are suffering from White Spot Disease, this medication is a must-have in your aquarium care kit. ๐ Highly recommend it! It saved my fish and my tankโs health!

Highly Effective
The API Liquid Super Ick Cure was highly effective at ridding my fish of the Ich infection. The instructions were easy to follow and after four rounds of treatment I was once again in the clear. My only criticism is that the liquid stains your decorations and appliances blue. my filter, Heater, and Airstone are all a cyan Blue and I think the warning on the packaging should be more prominent in order to not create issues with aqua scapers

Does what its supposed to!
We use API products in out tank. We thought this would help our green water problem. As I did help with most of the algae that accumulated from our live plants it did not help with the green water. This worked with our fish, frogs, goldfish, and live plants just fine. Our tank looks prettier with this product keeping the algae at bay!

Immediate results for me
3 of my 6 fish developed ick; the bottle says it treats 118 gallons, but I put 8 10ml shots in my 80 gallon tank and the bottle was empty. I removed the charcoal and bumped the temperature up to 82ยฐ and the fish were spry and looking 10x better the next day. It's dyes the water blue and requires a change of water eventually, but it's super effective.

Only one casualty
So I was gone on a vacation and when i got back I noticed all of my fish had clamped fins, were sitting on the bottom and that the filter had been unplugged.. the caretaker didnโt know how to deal with that. So I noticed 2 fish had ich spots, i did a 55% water change the night i got home and the next day a 20% change.. the day after that treatment arrived and i treated the tank. After becoming inactive 3/4 including 2 commons and one fancy perked right up, no longer had clamped fins, they seemed back to normal. The fourth was just sitting never came up from the bottom. And when i gave the second dose after 48 hours he immediately died. I do believe he was just too far to save to begin with. Its pretty easy to use, immediately improved the health within 3/4 of my fish. It turns water blue but then clears up! For the price, id expect more only because i got one use out of it for my tank size.

Excellent Ick cure
This save my fish from the Ich/Ick. We were treating him with a different product that was ineffective. With a few treatments he was back. It was a great feeling.

The nuclear bomb of Ich Meds - Use with EXTREME caution with sensitive fish
First, this has nothing to do with the white spots disappearing from your fish. Ich falls off your fish as a natural part of the ich life cycle; it then lands in your tank, hatches, and becomes free swimming and in search of a new host (fish) to infect. Like all ich medicines, this medicine works by killing the parasite when it is swimming in your tank in search of a new fish to infect. So you need to be very careful with timing and follow the directions; do not skip the second dose because your fish are clear. So far, this seems to have stopped an outbreak of ich that started with a new tetra I bought from a LFS I will never trust again. However, even at 50% dosage, this killed my Bolivian Rams. The rams developed red gills and struggled to breathe despite my running two airstones and a sponge filter in addition to my AC-110. This is basically the nuclear bomb of ich meds. Unless you're dealing with bombproof fish like zebra danios, I would start out with something gentler but still effective like Hikari's Ich-X and only move to this med if you absolutely have to do so.

Can be used in 2 months old fry tank
This medicine is actually a wonder-medicine, I should say, because it reduced the symptoms in one use. Usually the ICH medication or any other medication shouldn't be used in fry tank, but this time, I used it in Jaguar Cichlids fry tank (2 month old fry), in one day 90% spots disappeared! I used 4-5 drops in small tank and a pinch of aquarium salt. Then changed water after 6 hours. Again repeated the same. I am not sure if it is correct method, but it works. I highly recommend this for breeders. Thanks for this excellent medicine.

Effective treatment and easy to dose
This is a useful treatment to keep on hand if you have an aquarium. The instructions are straightforward, and the bottle makes it easy to measure the correct dose. I used it at the first signs of white spots and saw a clear improvement quickly. It is suitable for both freshwater and saltwater tanks, though it should not be used in reef aquariums. A reliable product from a trusted brand, and handy to have available before problems get worse.
