Hey AA guys. I could use your advice and information.
I have an algae problem that has gotten out of hand and now I really need some input to correct and, hopefully, solve the issue. The algae I have is the thick, smeary, dark-green algae on the leaves of plants and the glass, especially where the plants rub on the glass. The algae wipes off easily with a clean washcloth, but is back in a week. The algae will even come off pretty easy off of the plant leaves. I also have algae floating on the surface of the water. I also have some finger like algae on some plants. My water is clear, so not green water issues, but I run a UV light "filter".
Tank specifics:
125 gallon, two Rena Fistar canister filters
UV light on separate pump
384 watts of light, half for 10 hrs/day, full for 5 hrs/day on timers
pressurized CO2 with glass diffuser on timer with half and full light
well planted tank (a variety of swords but also some crypts & annubis)
community fish
Chemistry:
pH - 6.4
NHs/NH4 - 0
NO2 - 0
NO2 - 40 to 80
PO3 - 5 to 10
GH - 5
KH - 3
CO2 via chart - 35
temp - 82 to 84 (hot Arkansas summer, cooler during cooler weather)
Nutrients dosing:
KNO3 - 2.5 mL (1/2 tsp) 3x/week
KSO4 - 7.5 mL (1-1/2 tsp) 3x/wk
KPO3 - 1.2 mL (1/4 tsp) 3x/wk
Trace - 2.5 mL (1/2 tsp) 3x/wk
Iron - 1.2 mL (1/4 tsp) 3x/wk
Weekly care:
50% warter changes
GH Booster (Greg Watson) - 7.5 mL (1-1/2 tsp)
CaCO3 - 7.5 mL (1-1/2 tsp)
AP tap water conditioner - 30 mL
The chemistry has been pretty consistent for months now.
I know glass CO2 diffusers are not the most recommended, but it does keep my CO2 level up. Extra iron dosing is not needed, but my plants really responded well with the extra dose. I do use AP test kits, but also bought a SeaChem PO3 test kit to double check the AP kit and it read beyond the 3 ppm on the chart.
This week, I am going to cut back on KNO3 dosing to 1.2 mL, eliminate KPO3 dosing, and increase KSO4 dosing to 10.0 mL. folks here have recommended keep some KPO3 dosing, so I'll try to cut back for week, see what my levels are next week, and re-evaluate both PO3 and NO3.
What else can I do? What am I missing? What is going on? What can I do differently? What can I use to remove the floating algae (paper towel floated on top maybe)? Anything else you may want to know?
You guys here have always given excellent advice. I've gotten alot of poor and mixed advice from local fish stores, so my preference for advice is here with you guys.
Thanks for your time, information, and advice.
