Hi Chaps . . . . . I've got a problem. I've advised so many people on tackling algae problems etc etc and have never had them myself (well, apart from the initial cycle) . . . and now I'm being struck with them myself.
I'm getting cyno growing on the rocks and Bryopsis growing in all the nooks and crannies the tangs can't get at. Not only is this upsetting the aestetics of the tank, but it's growing inside some of my corals and also driving my PH down at night . . . . . . and I can't get rid of it. I'm running out of idea's and would appreciate any thoughts you guys have.
Water Params are
Amonia 0
Nitrite 0
Nitrate 7
measurable Phosphates 0 (And I run Rowaphos which has been replaced)
Calcium 480
Alk 2.5mgl
PH 7.9 AM to 8.3 PM
Lighting is 12 hours a day under 3x250W MH and actinics
I'm dosing Kalk to replace all evaportaion (approx 7Litres a day)
Redox approx 320-360
Feed lightly once a day and skim very heavily (and wet)
I stir up the shallow sand bed every day to remove detritus
Circulation is 18,000Litres an hour in 710Litres tank (Approx 22xflow)
35% water change once a month
Anyone got an thoughts, I'd really appreciate them
Thanks in advance
