Ok reef people. I've been missing in action for a while. Partly because I fished all summer and partly,mostly because of an algae nightmare.here it goes. I want some science involved with this. I have 2 4foot by 2 foot tanks. 10 inches deep. Both share the same sump,filtration, etc. I frag corals and place them in both tanks. Everything is the same. Lighting is on 10 hours. T5s come on for 1.5 hours then less. I ramp down the same way. 1 tank is pristine, the other,covered in heavy hair algae.i run 2 sumps. A 50 gallon with live rock, and a 30 gallon with refugium and chaeto.the rock sump had major algae growing in it. I have since removed that sump from the system. I run a large octopus skimmer wet and a roller mat system . Any ideas. I've torn the problem tank down,steralized everything and placed it back in line just to have the algae go crazy again in this tank only. So here are my parameters.
Calcium 593 adjusted the dosing down a hair
Dkh 10.3 adjusted a hair also
Nitrite 0 ph ultra low hanna tester
Phosphates 4 ppb ultra low hanna tester
Par 78 ramping up to 180 then back down
Manual removal every day of what I can get off the coral. All the sps are growing well and great .color. Softies dont like the algae .looking sad
Any ideas fellow reefers?
Oh,did the blackout thing. Made things better for a couple days then right back to the nasty stuff again.
