This is sort of a continuation from another thread but here it goes. I've just finished setting up my 25 gallon saltwater tank. There's what I believe to be kenya tree coral on apiece of live rock I bought. There's also a greenish looking coral on there as well (photos attached) I've seen them at petco before but I can't remember the name so maybe someone can help. Also wondering if my powerhead placement is correct in my tank for the corals? There's also 3 damsels and 2 emerald crabs. It's a straight upgrade from a ten gallon nano. IE: no new livestock has been added yet. Frankly I'm not sure if my tank can support any more. As you can see from the pictures, I've got a coral life 48 watt T5 fixture that has one 10,000K daylight and one actinic blue light. I'm also running a hob
filter, but I'm not sure if this is needed; looking for some guidance with that. This is my first larger saltwater tank so the lighting and filtration thing is a little new to me as its it's less of a concern on a nano tank. In fact I never had a skimmer on my nano tank, but I was hoping someone can point me in the right direction of which one to buy if I in fact need one for this tank; not sure if a hob
only will do it. Also, as a sort of random question, can I keep this light fixture over open water or do I need a glass top? I have one laying around if anyone thinks I should use it. Thank you from a newb!
