1. You can use a canister on sw
but most find that its more hassle than its worth, of course a sump would be best but we cant always afford the best or if we can we may not be able to get the spouses sign off. If its fowlr
to start you'll prob be fine i would suggest having a sump and ridding the canister before corals. ( some would disagree on canister though, so...)
2. If you dont like the cc switch it out now. If you use the lr
from the other tank it will lessen your cycle, most likely youll have a very small spike for a day or two and thats it. sandbeds dont help biofiltrationa whole lot unless they are deep. Also I have read that different bacteria grows in sw
than in fw
, so I don't think any bb on your sand would be beneficial to use. (or is the cc in your sw
and im confused about whats where) either way i'd switch it now, rather than later which may cause a spike by stirring everything up more than usual.
3. How deep and what wattage are your bulbs? My guess is that you wouldn't be able to grow sps
but most other corals shouldnt be a prob.
Can youhang the mh
off a pendant? Still give your tank a nice look while granting you better light. I know youre looking to get some money and the mh
is prob worth the most of your leftovers, butI think Id put it as my primary, just a thought.
Single reflectors increase light reflection over dual. What happen is two bulbs arenext to eachother and a portion of that light is going direclty into a bulb that has just as much light coming out making a percentage (about 20%) waste. So single is best if you can do it.
