B,
Thanks for the heads up on dosing. I wasn't going to purchase a calcium reactor anytime yet. In fact, I've been dosing manually since I placed my corals and critters.
Remember, I won several prize additives here on nanotank, and I'm finally taking advantage of them, Reef Calcium additive etc.
I told my wife that in the future when my tank is fully up and running I would consider the calcium reactor, just gave her an idea that I might get it. That way when I come home with the setup and she sees a scuba tank for the CO2, she won't think I'm crazy.
I will invest in the phosphate reactor because it's an easy setup and I hate phosphate in my water column. It's plug and walk away, and change the rowaphos when it's exhausted.
Regarding the fans, thanks, I've been looking for two fans to place in the back of my canopy. I cannot drill vents on the side of the plastic. In fact, it's too thin for that, but the opening in the back is perfect; all I have to do is just sit the fans on top of the glass lid, one blowing in and on the other side one sucking out.
The cooling fans on my fixture are on top, so when I remove the plastic lids the hot air rises and leaves, no problem. But because I'd like to leave the plastic lids on top, I need something to at least start pushing the hot air out as it will accumulate fast.
The back has two large openings, much larger than the fans, so I hope it would work. I'm looking into these two fans by coralife, tell me what you think?
