Fish transfer to large tank
Hi all, i just finished building myself a 250gallon tank for my freshwater fish. I have a couple of questions...:-) My old tank is 50g.
I filled my 250g tank and checked the ph which is 3.85!!! Horrible!! How would i raise the ph safely for my fish? Using bicab (baking soda)? I need to use everyday items due to the fact that my lfs is in the city which is 200km from me! Usually our tap ph is a stable 7.3 and is all natural from my borehole. But now it is like acid.
Then, how should i proceed in moving the fish? Currently in the 50g there are 4 clown loaches, 2 iridescent sharks, 2 synodontis, 1 pleco, 6 tigerbarbs, 2 gouramis and 2 angels. I know this is a very weird combination but it works. Can i just use the old filter medium and add it to my new filter and move The gravel and all the old water into the new tank?

is your tap still at 7.3. Is this a plywood tank?

Yes, plywood, fiberglass and flocoat. My tap ph is and has been at 3.8 since a week ago and not raising. So i can not depend on my tap water to raise. It might still raise after rain but i am tired of waiting.

Its normally very stable but it hasn't rained in a while. Been fine for the 3years ive been keeping fish. Okay, google is giving me better answers on the ph, now how about moving the fish?

The old filter media will be fine considering you haven't added any new fish - it has enough bacteria to handle your current stock.
Moving the gravel will also be good, however, the water doesn't need to be moved - there's no bacteria in it. Although perhaps it might be better (I'm thinking out loud here) if you did that for pH stability?
If you put new water in there, you would probably need to acclimate the fish first.

Thank you for your advice, thats what i thought as well, i just find it very strange that my water is acid. But now i am planning a rainwater supply for in case my ph doesn't stabilize. So if i stabilize my tanks' ph then i can move the fish? Great! Well, good night and any other advice is welcomed!
