I Have a 150 litre tank as follows:
- 4 beautiful fantail goldfish about 5cm long.
- Eheim canister filter.
- Gravel substrate.
- Live plants.
- A couple of shells.
Pic attached...
The tank is still cycling (fish-in cycle due to urgent need for a larger tank).
The problem - I have a consistently low ph, which is not ideal for goldfish. It is 6.4.
I tried adding the two shells a few weeks ago, to no effect.
The tap water is at about 7.5 to 7.8.
I asked at a lfs today what to do about it. They suggested adding a powder, but I read somewhere that this increases the ph too quickly, and that is very bad for fishies.
I don't think I can add anything to the filter as the canister contains trays of particular things.
Is there anything else I can do?
