I setup a 90g barebottom (bb) tank about .. I guess 6 months ago. I've been having terrible algae problems, another story..or possibly related.
I have around 850-950 gph
circulation just with my return pump from my basement sump...I also have two modified MaxiJets (nozzle sawed off) that in theory add about 100 gph
each of flow.
Every week I take a maxijet and move it around the tank to kick up things off the rocks and the bb, and then do a water change (I siphon water directly out of the display).
With a bb, if I do NOT have constant/continual huge flow on the bottom, to make sure everything is "kicked up" and exported through filtration, am I causing perhaps some of the problems I'm having with algae (hair algae)?
my params are all great - nitrates/ammonia/nitrites = 0, salanity pretty steady at 1.022, pH usually around 8.2.
I have been thinking of "starting over", taking out all of my rocks, and putting a dsb
in the tank. My prior tank, a 37g FOWLR
, seemed to thrive for about 2 years with my dsb
, live rock and small protein skimmer.
