Review: The basics dont get better than this! MUST HAVE - I’ve used Stability across multiple tanks and it’s become a staple in my routine. It reliably helps establish and support the beneficial bacteria that keep ammonia and nitrite in check, so day‑to‑day running is smoother and fish stay comfortable. What I notice in real use New setups settle more predictably, with fewer “new tank” wobbles. After filter cleaning, media changes, or adding new fish, the tank stays stable rather than spiking. No clouding or residue; it’s clean and easy to dose. How I use it (simple routine) New tanks: shake the bottle well and dose per label for the first week. Maintenance: add a dose after larger water changes, filter clean‑outs, or when swapping media. Extra protection: a top‑up when introducing new livestock gives the bacteria a helpful boost. Why it works for me It’s “set and forget”: no special storage fuss, and it plays nicely with sponges, ceramic rings, and premium biomedia. Scales to any filter—HOB, internal, canister, or sump basket. Great value when you run more than one aquarium; the bottle stretches a long way. Tips for best results Put mechanical filtration (sponges/floss) before your biomedia so debris doesn’t smother the bacteria. Don’t over‑clean: rinse media in old tank water, not tap water. Keep good flow and oxygenation; bacteria thrive in well‑oxygenated water. Follow the label, and if you use UV/ozone, pause it for a few hours after dosing. Verdict Simple, dependable, and effective. Stability is the bottle I reach for whenever I start a tank, refresh filters, or just want extra peace of mind. It’s earned a permanent place in my kit—highly recommended.
Review: Reliable bacteria booster—keeps tanks stable during cycling and water changes with zero clouding. - Used this during a fresh setup and again after a major water change—didn’t lose a single fish. Dosed as directed for 7 days and saw no ammonia or nitrite spikes. Water stayed clear, fish stayed active, and no weird smells or reactions. I’ve used it in both planted and bare-bottom tanks—works well with cichlids, shrimp, and fry. Doesn’t cloud the water, and it mixes clean. Bottle’s compact and easy to stash, and the dosing cap’s accurate enough for small tanks. It’s not magic, but it does what it says—keeps things stable when you’re starting fresh or making big changes. I keep a bottle in the gear stash for emergencies and new builds. 👍 Pros ✅ Fast-acting—supports tank cycling and resets ✅ No clouding—water stays clear ✅ Safe for all fish types and inverts ✅ Compact bottle—easy to store ✅ Works with planted and bare setups 👎 Cons ❌ Needs daily dosing for full effect ❌ No visible change—relies on trust and test kits ❌ Cap can drip—wipe after use ❌ Not a cure-all—still need proper filtration 🧭 Personal Review If you want a bacteria booster that keeps your tank stable without the faff, Seachem Stability earns its spot. I’ve used it across new builds and heavy water changes—no drama, just clean results and peace of mind. Proper stash-ready gear for anyone who wants their tank sorted and stress-free.

## Questions & Answers

**Q: How long do you leave uv light off for after adding this please?**
A: I usually turn the UV light for 24 hours.

**Q: how many capfuls for a 60us gallon tank?**
A: I do 1 cap for my 200 litre tank 👍

**Q: Will this help Cloudy water?**
A: Stability is not for cloudy water. I use Seachem Clarity for cloudy water OR better still a water change with prim and stability.

**Q: How often should I use this product**
A: If your tank is cycling, you can use it everyday for 7 days. Adding a few fish on the 3rd day. You have to read the bottle for how much stability to use verses the size of your aquarium. If your tank is cycled and mature you can use it after you do a water change.

### ⭐⭐⭐⭐⭐ I’ve been really impressed with how well the Seachem Stability Tank Stabilization System
*by L***E on 2 January 2026*

I’ve been really impressed with how well the Seachem Stability Tank Stabilisation System works in my aquarium! This product makes establishing and maintaining a healthy biofilter so much easier, whether I’m setting up a brand‑new tank or giving my established system a boost. Stability contains a powerful blend of beneficial aerobic, anaerobic, and facultative bacteria that help break down waste, ammonia, nitrite, and nitrate, which is vital for keeping water quality stable and fish thriving. What I particularly love is how gentle and safe it is; it’s completely harmless to fish, plants, and invertebrates, and there’s no risk of overdosing even if you accidentally put in a little extra. The dosing is straightforward, and I’ve seen noticeable improvements in water clarity and overall tank balance after using it during water changes and when cycling new setups. Overall, it’s a dependable, high‑quality product that gives me confidence that my aquarium’s biology is well supported, every day. Highly recommend for both beginners and experienced aquarists!
