I have a canister on the 155, just an internal on the 50 I have a canister on the 155, just an internal on the 50

Well I thought we'd always had high nitrates in the tap water, when I tested it a few years ago they were between 20-40ppm. I've just tested it now because I was doubting myself & it's come out at 10ppm. My 50gal always hovers around 40 & my 155gal seems to now be doing the same. So do you reckon I can add the fish I've got & keep a close eye on it? I'll pick up a bottle of water tomorrow & test it too Hi! It's a Fluval U4 & it could do with a clean out anyway, perhaps I'll do that tomorrow

Hi! It's 8.0

Thanks for the reply! It's a 6ft 155gal running a Fluval FX6, airstone, sand substrate & set to 25°C. I have got an old 50gal that's been set up for years & currently has a bristlenose pleco, synodontis, & 3 kuhli loaches in it. I had wondered about just putting them in the new tank with their current internal filter as well & then monitoring closely but I want to keep the 50gal set up as a quarentine tank for new fish. Could I then put a filter that's not currently in use on the 50gal as there's a lot of bacteria in the substrate & on decor? Picture included of the 155gal 😊

Hello from England! I'm so confused with cycling, I understand the nitrogen cycle & how it works but I fall short when applying it to my tank! It's been up & running since 15th December, I added beneficial bacteria on the day & then added plants on 4th January. Between this time I was testing & getting funky results which is when I looked at the dates on the bottles, 3 years out of date, oops! So I've ignored all of the results & bought a new test kit, these are my parameters now: 07/01/2023 Ammonia 1ppm Nitrite 1ppm Nitrate 40ppm 50% water change 08/01/2023 Ammonia 0.2ppm Nitrite 1ppm Nitrate 40ppm 11/01/2023 Ammonia 0.2ppm Nitrite 1ppm Nitrate 40ppm I think I screwed up doing the water change but to be honest I really don't know what I'm doing & everything I've learned over the past 12 years seems to have left my brain. Also we have high nitrates in the water, they usually sit at around 40ppm. Any help is appreciated!
