Thanks jaws. I was just pointing out what I've seen debated recently and what I see that makes the possible cons relevant. People also go back and forth on seeing Spikes. Some Purigen users say they've had them others don't and swear by Purigen.
Remember your lettuce is competing with the algae for available resources. So that maybe some of your issue. Are you fertilizing? Or just relying on the organic waste from the fish?
Jaws can what method you've used to create anaerobic bb in one of the towers?
I moved the lettuce to another tank with a much smaller bioload that already has 10 ir so WL plants and had shown some decent reduction in nitrates. Figure it would do more for me there than in the large sump thst was accumulating all sorts of algae, plus the bio load is much higher.
Im gonna try the purigen in a submersible filter and see how it does with the higher flow rate.
Havent gotten to the the anerobic filter yet but have all the materials just need time to start it.
I think the pressure will be reduced if daisy chained together. The denitrate is flow dependent 30-50 gph. Filter floss is ok but will need to be replaced. It'll clog quick. I think one tower with media and one tower with foam or filter floss would be the go. The tower with media would be the first tower to get water from the pump as well.
Not disagreeing but ive read that the foam or mech should go first so that the media doesnt become clogged over time.
Yeah the floss is just because im impatient amd the foam wont arrive till mid april..smh
I thought the longer the water flows through the filter the more oxygen will be depleted that was the reason for the 3 towers and the media being in the last...
Dunno am i looking at the backwards. Wouldnt be the first time lol
