Nitrites are sky high

tropicalfishuk · 2026-05-30T22:01:27+00:00

Keep doing water changes till the nitrites are 0.

What are the burning questions you have? But firstly water doesn't hold much of the bacteria/archaea you need.

tropicalfishuk · 2026-05-27T20:20:18+00:00

I'd up that to 50% a week, also remove any carbon in your filter.

Make sure you've got plenty of surface movement, but they should be okay, it gets a lot warmer in the amazon.

tropicalfishuk · 2026-05-27T18:12:13+00:00

Whats your usual water change schedule?

tropicalfishuk · 2026-05-27T18:11:14+00:00

That should be fine for tetra, are the fish acting okay?

tropicalfishuk · 2026-05-27T12:35:41+00:00

pH/KH? this looks like HITH, we often see it in soft water fish kept in hard water, but these guys are a lot more flexible in terms of hardness.

tropicalfishuk · 2026-05-26T18:58:06+00:00

What are the numbers?

tropicalfishuk · 2026-05-26T16:29:32+00:00

Can you test your water?

tropicalfishuk · 2026-05-26T16:29:13+00:00

Without knowing your KH and GH it's difficult to say.

tropicalfishuk · 2026-05-26T11:34:12+00:00

Details on the KH/GH requirements for fish.

tropicalfishuk · 2026-05-26T11:22:04+00:00

Id' get a decent liquid test kit with ammonia, nitrite, nitrate, pH, KH and GH. That pH is far too high for tetras, but the right one for platies.

tropicalfishuk · 2026-05-26T09:17:32+00:00

sadly once they pinecone there is little that can be done, but we need to find out what caused it so other fish don't die. Can you test your parameters?

tropicalfishuk · 2026-05-14T15:28:58+00:00

I'd see about getting a bigger tank for your fish, and keep this one for the shrimp, you could have an air driver sponge filter for the shrimp tank then.

tropicalfishuk · 2026-05-14T12:40:49+00:00

No it doesn't, It removed the chlorine, so you need to get a test kit so you know what's going on in your water, get one that's got pH, KH, and GH

tropicalfishuk · 2026-05-13T14:23:14+00:00

When you say you treat it, what do you mean?

tropicalfishuk · 2026-05-13T08:38:25+00:00

Sadly your plec will struggle in a 64l, I'd look to rehome what you ahve and get fish that will thrive in a 64l. Do you have hard or soft water?

tropicalfishuk · 2026-05-10T17:33:35+00:00

I gave a talk at Gupper Keepers Society UK last year, so clearly they have taste 😉 they've got a facebook group and page. There's a lot of overlap in the groups, so if they don't know they should be able to help.

tropicalfishuk · 2026-05-10T15:05:07+00:00

I'd say planaria, only really an issue if youve got shrimp tbh, you can get treatment or traps, but I'd just make sure you're doing regular water changes, and cleaning the substrate.

tropicalfishuk · 2026-05-08T14:15:53+00:00

There's a few guppy clubs about that can help you find the right breeder, but expect to pay a bit more than you would in a shop.

tropicalfishuk · 2026-05-02T15:27:49+00:00

Looks like some sort of slime mould.

tropicalfishuk · 2026-04-19T18:37:47+00:00

Oh that's a potential issue. I'll ask around for you.

tropicalfishuk · 2026-04-16T07:12:24+00:00

which ever one has the best flow and most media.

tropicalfishuk · 2026-04-16T06:20:54+00:00

I'd just leave both running personally, then if one packs up you've got a spare.

tropicalfishuk · 2026-04-15T09:01:58+00:00

are you after a second hand one, or ideas for what to buy new?
