Hello to all and thanks in advance.First let me say this site is awesome..thanks so much for it.OK..I have a brand new 75 gal fowlr.The plan was to buy LR uncured.Luckily, LFS called said have cured for same price.Apparently a friend was breaking down tank, here you go.Great deal.But the guy, an actual marine biologist,said tank would be ready for fish almost immediately.So it was running with live sand and water for about 3 weeks, LR added 1/28.Tests are 0 amm,0 nitrite and 10 nitrate.Ammonia never spiked.So I added 10 snails and 10 hermits yesterday.Doing great on some algae that started.Just want to make sure before I add a fish..don't want a casualty.And if I do still have to cycle,can cuc stay in??I NEVER had any ammonia show, tested every day.
