 Re: Newbie with lots of questions.
welcome to the forum
the prizms are decent skimmers for the price there are much more better ones but that all depends on what you can spend. if you can go for the higer end models go for it. you actully do have quite a few critters for only running 4 weeks best thing is to slow down and quit adding things for a while your tank needs to level out.
corals should actually be added to the tank later, for the first couple months or so you wil have many different alge phases and most of them can kill and suffocate corals. as far as fish you should add 1 or 2 at a time no more than that because each fish adds to your bioload and that needs time to even out also.
for your cyano its a pain to get rid of add circulation, dont stock so fast, dont over feed, increase smaller more frequent water changes, check phosphate, nitrates, and silicates. with having new lights its probably not part of the problem. but check any of the above all of them can add to it. also use your skimmer and to keep up on it you can use a turkey baster to suck the alge out. it comes back but it helps from building up. |
