Lowering pH

[FoundMoney]

I have a newly established 30 gallon tank and the pH is pretty consistently at 7.2. Currently the tank has 8 Flame Tetras and a Bristlenose cat. There are also some plants, hornwort, dwarf sag, Vallisneria, anacharis and a couple of sword plants. I wouldn't say it's heavily planted but it's not sparse either.

I'm considering adding a pair of dwarf cichlids to the tank but I'm wondering if the pH is too high. I've read that the Apistogramma cacatuoides can handle a bit higher pH but I might not want to be limited to those fish. Should I worry about lowering the pH and if so, how should I go about doing it?

How are the tetras? I believe those are from south america and would be used to a lower pH If your pH isn't too, high, but that's just my opinion. To be safe, acclimatise any fish used to a lower pH for a longer time than you would usually

Yes, they are South American and in their natural habitat they would probably be used to a pH of around 6.5. However, from what I've read they can tolerate a pH as high as 7.8. Ideally, they would probably be better off with a lower pH but they seem to be doing fine.

I've also read that they would prefer "peat filtration". What is that exactly and would that be an effective way of lowering the pH slightly?

I've also come across using "R.O" water for water changes. Is this recommended and where do you get R.O. water?

Peat filtration is to soften the water, not change the pH.

pH lowering chemicals are available at stores.

I noticed my local store is selling a product called 'Bullseye' which will alter pH to any desired target. They have 3 types at the moment. One for 6.5, one for 7, and one for 7.5 (I think). I am thinking od trying the 6.5 one - am I am just about the same situation as you (7.3 and wanting to lower pH).
