I have had a problem with Diatoms and BGA for over 3 months now. I tested my tap last month and found that I have phosphates off the charts. I tried a few products in my canister filter to help with the phosphates but everything sticks around as I do my weekly water changes. I feed lightly and my tank is full of plants.
I picked up a DI unit from my LFS. They didn't have RO units. I know that the resin will expire quickly because my phosphate levels are so high, but I don't know what else to do. They offer refills. I also bought a TDS meter and it is in the mail.
Correct me if I am wrong, but from what I understand, the water from a DI will come out with a PH of around 7 or a little lower depending on how long it sits, and it will have a KH/GH of 0? This water needs to be reconstituted with the proper minerals for my fish and plants as well as buffered so that I don't have any ph crashes?
Seachem Equilibrium should provide the proper minerals, but what about the buffers? If I am already keeping my tank at a PH of 7 with Neutral Regulator during my weekly water change, will this be sufficient for the DI water as a buffer? Do I need to mix DI/tap over a period of weeks or can I just start using it right away?
Is there anything else I need to consider before using this unit? It was an impulse buy and I wasn't educated. Now I am trying to figure out the best way to make it work for me.
Thanks for any advice.
