I will be getting the" PH down" and trying the Peat Moss technique to bring it down for now. I assume the wood that will be in it in approximately a week or two will be sufficient to keep it stable. There will be a large piece of Mopani in the Center of the Tank. I've heard that this type of wood could cause some issues but the look is great and I wanted to give it a try. Unfortunately , I don't want to introduce any fish into the tank until I get all the perameters stabilized. Also, In an effort to keep the PH down I use Reverse Osmosis and/or distilled water for water changes. This worked pretty well in my "Trainer" 10 gallon tank. It also seems to be bland Nuetral water with minimal additives. I still add the water conditioner and Bacteria though.
Be very careful with pH Down or any similar chemical. These frequently do not work due to the buffering of the KH. What happens is that the pH Down lowers the pH, then the KH raises it back to where it is in the source water. Then you add more pH Down, but the KH raises it back up again. This will continue to occur until the point at which the buffering capacity of the KH is reached, and then the pH can suddenly drop, what some refer to as a crash, because there is no longer any buffering to affect all the chemical solution.
The latter crash will almost certainly kill the fish. But leading up to that, the continual fluctuations up and down are highly stressful and these weaken the fish.
It is best to use these solutions in tanks without live fish. If after say a week the pH is remaining stable, it should be safe.
