hello guys, just got my 250 gallon tank and boy its a monster.so here is my little problem. my well water is about 6.2-6.4 when i bought the tank i filled it and cleaned the crushed coral that came with the tank and put it in. i then found out that it raised ph. its at about 7.4-7.6 now maybe higher. is it going to countinue to climb? i keep piranha so i want it a little lower. i took as much out as i could there was a few cips left. i layed sand back down. the lfs said its better that i let them get used it it and not try and brang it down. any advice!
