    Ammonia not spiking during cycle

    So 2 weeks ago I started my 69 gallon tank with dry Marco rock, live sand, Dr Tims One and Only, and a cocktail shrimp. After 3 days I began testing and I seen no real rise in ammonia and a very small rise in nitrite. At the 1 week mark I pulled out the shrimp and replaced it with a raw shrimp...

We started fish in and after learning our lesson took them back out about 3 weeks ago but left a few hermit crabs in and I dose with prime every couple of days. The ammonia has been high the entire...

    Nano Build New reef questions

    Hello all! So I used to have a reef tank and had a very “text book” cycle, ammonia rises, then nitrite, then nitrate, then a big diatom bloom and a die off. This time around I had the same chemistry, but no diatoms, it went straight to a dusting of green algae. It’s been about two months and a...

    Sustaining a newly-cycled unstocked tank?

    Hi all, I did a fishless tank cycle and am getting some nice diatom growth. I am going to wait until after the first of the year to stock my tank, but obviously want to keep the cycle going. I'm assuming I need to continue to add some ammonia every so often to keep it going? Has anyone done...
