Was looking at the Jager heaters but from all the posts I seen the Jager is too tall for this tank. What heaters are others using with this tank? Decided on the AI Prime HD for this tank which from my research should be plenty of light for most corals but always have the option of adding another AI Prime if need be which is nice. How are the AI Nero 3s on this tank? The reviews are solid and I really like the looks of them as well. Would I need more than one? For saltwater I’ll probably do LFS at first until I can get a good 5 or 6 stage RODI as my water quality in my condo is so bad I have to drink bottled water. Tap water is actually foul to even drink for humans so it’ll play hell on a RODI system without enough filtration. I see PETCO also sells saltwater premixed by Imaginatarium, has anyone had luck with this? The only LFS I know in the area that sells premixed saltwater charges $1.25 a gallon for instant ocean saltwater and $1.75 for Red Sea mixed water. I bought the book suggested by another user, Saltwater Fish and Reef Tanks: From Beginner to Expert and have been reading it since I got it on Kindle today. My tank hasn’t even came in yet but I want to take my time and only buy things once instead of having to purchase something that doesn’t work the way it should and having to repurchase it later. As for the heater I keep my home at a constant 70-72 degrees as the Axolotls like it could and truth be told so do I. So I think 100watts should be sufficient but it appears most 100watt heaters are too tall for the small chambers in the sump of the Lagoon. Thanks everyone for all the help.
