I built a upflow algae scrubber today (this is version 2 lol)...
sump end view...
algae scrubber ver. 1
view from the left end...
FTS..
I'm having problems with sand blowing and the diatoms are starting but everything else seems to be going good. Next is getting the ATO tank in, the dosing pump and chambers installed and skirting the stand.
(and tear down the old tank
)
