Here's a different approach...
Zach. what is in your 20g tank and does it still have ich? Also what are the water parameters for the 20g....ammonia, nitrite, nitrates, ph and salinity?
Just bear with me zach, I'm going somewhere with these questions...
And by the way, where are the pictures of the tank and stuff? We really wanna see what you've done so far.
180g Reef - 60g Rimless Reef -90G FOWLR- 125g Malawi Cichlids- 40b REEF- 34g Fresh Planted-working on- 20L FOWLR- working on
I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
