Great thread! Been reading this one for a few days now. Thank you for sharing your wisdom, over and over again. Your patience is without bounds. I actually started taking notes for my own notebook. At any rate, I have been working on my setup for a 65 gallon FOWLR - finally have all the equipment now (and an empty wallet...but don't tell my husband. Thus far my Don't Ask, Don't Tell policy seems to be working) ;-)
While I was waiting for various parts for my DT to arrive, I got impatient so I set up my 10 gal. QT and started it cycling. I am using an Aquaclear 20 and a powerhead. In the AC20, I have all three components (the sponge, carbon, and BioMax pellets). I am running the carbon to clear up the bacterial bloom caused by my shrimp. I know to take it out for meds. But I thought I read here that perhaps I should just fill the HOB with ceramic rings instead.
Question 1: Do you recommend using more ceramic media IN LIEU of the sponge? I know the sponges get clogged and need to be rinsed or replaced (though I know not concurrently with any of the other media in there). Does ceramic media NOT have to be rinsed or removed ever? Can I get away with NO mechanical filtration in the QT?
My overall plan is once I get my DT up and cycled, that I keep a separate bag of ceramic media (or extra sponge if you think that is good) in the AC70 to be used in my QT's AC20 for when I need to swap out the the AC20s media for cleaning etc since I don't have a sump to store these things. I will be running a skimmer on the DT and the rock with be the main bio filter for the DT. The DT HOB will primarily be for a place to keep backup seeded media for the QT and also a place to put carbon or for phosphate remover for the DT. Does this sound like a sound plan?
Question 2: Once my 10 gal. QT is cycled, should I decide to want to keep a PJ Cardinal in there to keep it cycled, can I put the Cardinal in with 2 small Oscellaris clowns in the 1QT or do I need to add the Cardinal first, dose with Prazipro etc. follow that protocol and then if all goes well, do WCs, run carbon to get rid of the meds and THEN add the clowns to the QT and start the whole process over? Thanks in advance!
