So I just changed tanks. Got rid of old sand and replaced with new agraalive. Reused old tank water with addition to fresh salt mixed to compensate for additional tank volume. No new fish no new coral and I believe I have ich on one fish so far. The previous tank was running for a year and no ich period. I have no qt atm since I just moved. Is it possible I got the ich from the sand or just stress from moving tanks. Also what can I do to treat my dt. Tia
