I have had a chronic algae issue and have tried just about everything I can think. So, any help is greatly appreciated.
Tank:40 gallon "breeder tank" reef aquarium established for approx 1 yr.
Lights: 96X2 watt power compact
Water Movement: 75 gallon sump pump, Koralia nano powerhead, Koralia 600 GPH
powerhead, protein skimmer
Salt: Kent Marine with 1.025 salinity
Substrate: 40 lbs sand, 40+ lbs live rock
Fish: Clown, sand sifting goby, angel fish
live stock: coral banded shrimp, 2 peppermint shrimp, 1 male 1 female emerald crab, approx 20 snails, approx 20 hermits
Coral: mushrooms, open brain, yellow polyps, bubble, colt, Green Frogspawn, torch coral, flower
Chronic (6 months) algae growth
Appearance: brown/rusty algae growth on sand and glass. Growth will get quite heavy on sand.
pH: seems too low
, 79 degrees, tested with Quick Dip strips (0 nitrate/nitrite, alkalinity approx 180, pH 7.5-7.8 despite treatment with Kent Marine Superbuffer)
I HAVE TRIED
replacing bulbs, increasing water changes (every 2 wks), red slime remover, tank clarifier, adding the powerheads, adding to the deep sand bed, adding superbuffer
