Hi Everyone, I posted a while back about having some green algaee on my sand bed. Well now it has gotten worse, and then worse. I have a 29 gallon bio cube and have done 2 15 gallon water changes in the past 2 weeks and stil no luck. I have cut feeding down to 3very other day and am changin media filter floss every 2 days. my lights are at 10k no green or red and running only 8 hours a day. I got a new skimmer to help with the bio load, did the eshopps 75h, love it so far. I was thinking about doing a reactor? My question is do you need a sump for a reactor, or can i just use it directly on the bio cube? Here is a picture of my tank. The algae is even on the snails! looks like hari algaee from what i have read. the corals are doing good, LPS is puffy and full and the zoas are thriving. Got some Blue Tubs, Eagle, and Fruit loops on the white circle frag. My brother in law also gave me the them along with them mushroom on the sand. This picture was a couple of days ago it is a lot worse now! I clean the whip every day so the algaee does not hurt it..Need Help thoughts and opinions!!!! Thank you!!
