i have yet again, dark red cyanobacteria on the rocks and sandbed. im sick of this stuff, i just cant seem to get rid of it. i had it several months ago and dosed (1/2 the recommended dose) of anti-red which seemed to get rid of it - or so i thought. my tank is only 80 gallon and i know its overstocked (bought it 2nd hand already with fish and LR
) and so am moving to a 140 gallon tank (or 260 gallons with refugium and sump) in the next couple of months. the cyano
appears quickly and then disappeared off and on for a few months. this time its on the rocks as well so is a pain to get rid of. i have a deltec 1060 skimmer (rated at 260 gallons) and appears to be working well.
i have read huge amounts of info on the web about cyano
and the main cure seems to be physically removing as much as possible then doing several and more frequent water changes over a period of several weeks. i do have high nitrates (because of overstocking) and a small level of phosphates but ive also read that cyanobacteria is the only type of algae that is not directly related to high nitrate levels. if this is true, how come this stuff keeps popping up? i added an aquamedic nitratereductor a week ago to assist in reducing nitrates until i get the new setup (although have to wait 6 weeks or so apparently before it starts making any effect)
im keen on getting the new tank / refugium and sump setup as quick as possible to maximise biological filtration and get back to normal stocking levels. anyone else whose had cyano
and can throw in their 2 cents worth would be much appreciated!
