Lots of green on sand bed, what will clean it up?

[capaccvd]

I have found more of this growing on the sand bed of a 75 fish only tank.
I have had high nitrates for some time now, trying out the new Natural Nitrate Reducer by Instant Ocean, but it has not dropped. This is the second month of trying to manage nitrates with this product.
Can you suggest a good seeweed/alge eater? or is this something good to have in the tank?
PH: 8.2
NH3: 0
No2: 0
No3: 20

Holy crap. I would vacuum it up just keep the siphon on the top portion of the bed without disturbing all the settlement underneath it. After that I would then lower your Nitrates using Chemi-pure and Phosban. Then get yourself a diamond goby to keep your bed clean.

What kind of water are you using? That kind of problem is often seen with tap water users. You should only use RO (reverse Osmoses)
Also you need to possibly increase your water flow current. Phosphates and over feeding are the other causes. Water changes and lowering your phosphates, and increasing the water flow should clear it up…A sandsifting goby will not help that kind of mess. If you don’t fix what caused it you will be fighting a losing battle.
Get a small bucket and put filament fiber in it. Get a turkey baster and suck it up with that. Squirt the stuff in the filament it will catch the algae and you can pour the water back into the tank so you don’t lose too much saltwater.

Three demsels, and two clowns...ouch. Hair algae on the sand, two things. Poor circulation, and no vacuuming. 20 nitrates is not that bad, but if u have no refugium, its party time for the hair algea. IMO, only way to fight nitrates are water changes, and then you could use products to control it. The chemicals are designed more to control it, rather then fight it. It doesn't matter, if you have nothing to compete, or eat the algea, it will keep coming back.
