I love fixing things that arent broke, yet.
0 Nitrates is likely to be due to that brown film junk eating it. Im willing to bet the nitrates are just high enough to support one thing and thats why there is very little else growing. (Cheato is the other).
Maybe I will remove all the sponges and see how things go before making a mini DSB
I did win a new in box Aquatic life 115 skimmer for $31.00 on ebay. Maybe that will also put a damper on things a bit?
So what all is needed for a DSB
to operate? Would the water through the canister be too fast for a DSB
to develop? Maybe slowing down the water would help? Or maybe just leaving the thing empty of sand, rocks, sponges will mean more room for water and that actually be the real benefit?
