Fine as in no more fish?? I would like an idea for maybe a couple of very nice looking, colourful, peaceful fish that would be ok either on their own or as a pair, ideally that would grow to a maximum of 3inchesThat stocking sounds fine.
Tank looks lovely. Let it grow out a bit. O2 on after (at the time of) lights out. During the day, lights on (photoperiod) plants produce O2 and use CO2, equilibrium. Plants use O2 when they don't photosynthesise. They create CO2 which can decrease pH as the carbon molecules bind with the water. This will help balance the system for a given 24 hr period. Length height width of tank? Label each dimension. This is for stock cap, people may advise Gallons per inch, that can't work as a square tank and an oblong tank of the same volume are capable of sustaining different quantities of the same fish. They never look right the first time, or the second! You are being creative with natural objects and getting the look you want is difficult. Some settling on a happy medium here. River cats knows her plants, she may suggest to you something's that will work. (You don't have a tank like that and not know plants, plus I read the thread on tiger lotus) Lava rock may buffer your pH to alkaline, I'm not if sure it's inert, again others may know, if it buffers the water you will be fighting a losing battle trying to achieve neutral to acid conditions with alkaline rock.
Ok i try to answer most things. The bubbles come on as youve mentioned after my lights go off. Im pretty good with the biology of plants so thought this would be best. I think the tank is 60cm width, 60cm height and 46cm depth. I think. Anyway its a Fluval roma 90. Yes i do have alkaline ph but thought this was more to do with the hard tap water
Its only a tiny one. 90litres its all i could fit in. I havnt looked into blue ramsWhat size is your tank? After the tank is 4 months mature a pair of German Blue Rams would be nice for a touch of color and the right size. But they are very sensitive to nitrates which need to be kept at 20ppm or less.
Lava rock is inert.

6 neon tetrasThat is about 23 gallons so how many of each species do you have in the tank now as that will actually determine what you can add.
Yea i do id say about 40% every sunday as it is. Yea i was after a bigger fish as the centrepiece and thts tht until i find space to have a go at marine. Id love to have a go at thatFor that size tank and that stock IMO your pretty well stocked but if you do weekly WC's of 50% you should be able to add a pair of GBR's but that's about it.
