It sounds like you're off to an excellent start. Are you having a nice amount of coralline algae growth yet?Ok my 125 gal fowlr. Sad far I have two HOB reef octo skimmers bh-2000 both rated for 150 gallons and I have two ac110's one with purigen and floss and the other wig rock rubble. I also have 120 lbs of rock and two 950gph power heads. The sand is agronite and so far the tank has been running for 8 wks. The only inhabitants are two clown fish and six reef blue chromis. I changed my mind on the predator tank because I want to go reef. Now I have a couple questions. Do I need this cheato algae to have a reef setup? Also what else would I need besides lighting? Also would T5 HO's be enough let's say 4 lamp or do I need another type of bulb? Please assist me however everything is going amazing and I plan on ordering more reef safe fish and then getting some begginer level coral. Thanks
Chaeto algae isn't necessary, but it's super useful, especially in a reef setting; it helps with the nitrates & phosphates and provides a home for 'pods which are a great food source for corals & other reef-dwellers. As for your lighting, it all depends the bulbs (type, quality, & quantity) as well as the distance from the corals to the bulbs; you might be able to grow low-light corals towards the top of the aquarium with just a four bulb fixture, but you will not have much luck further down or with corals that need more light. At this point in time, I would go with LEDs as they've really come down in price & can support any type of coral provided that you buy the right fixture(s).
Oh, and we need to see some update pictures!
