stoping bba in established tank
 
i have a 75 gallon tank
no co2
flourite substraight
under gravle filter powered by 1 air stone and 1 tiny powerhead
high nitrates
low nitrites
gh around 150
kh around 80
ph 6.8
dose flourish every other week (going to stop, high iron)
anything else is unknown

2 zoomed bulbs
36-watt 5500k daylight bulb
32-watt max plant growth (5000K) bulb
directly on the top of the tank
dont have the budget for a stand to raise it
lights are on for 10 hours a day
maybe to much lighting


my first thought was just take out infected rocks and soak them in a 50/50 h2o2 and h2o sulotion. and get some S.A.E. but they would need to eat fast as i have a bullhead catfish that will eat everything in the tank.

I feel like the addition of pressurized co2 would help. I have the same issue and its only getting worse, so what I'm going to do is everything possible to allow my plants to have an edge over the BBA

I'm not even sure if siamese algae eaters would do anything for bba, nor do I think that there is any animal that would eradicate the issue completely

Is your fixture high output or normal output?

flesxruoyxllik 11-03-2012 11:13 PM

the light fixture is an achripelago lighting model SL-3 120v - .8 amps - 60 hz
i have no idea if its low or high output

GOOD LUCK!!!!! I have had my tank running for 3 years. IT went away but is back and not giving up. CO2 is as high as it can go, nutrient are perfect WCs every week 25-50%, overdosing excel and it's here to stay.

Doesn't matter what you do... BBA will show up no matter what.

ive had some success fighting hair algea with excel but that was a smaller tank im gonna need a big bottle to o.d. this 75

or should i do this
a diy co2 with a 2-liter bottle for a yeast grower, another connected with hoses going into some water to collect that white slimy gunk ive seen with some diy. finaly into the tank with an air stone difuser that i can move around to trouble spots, mainly rock caves and ugf tubes.

flesxruoyxllik 11-05-2012 06:10 PM

so i decided to use excel for a co2 source.

will raising my kh ( currently 50-80ppm) help to slow bba?

Dave6265 11-05-2012 06:24 PM

Cut your photo period... I have the zoomed 2x t5ho fixture on top of an 18" deep tank, and anything over 9 hours photo period and I see BBA.

My second suggestion would be a cleanup crew, but it seems like that would make a quick snack considering your livestock.

What are your nitrate readings? I had an undergravel got rid of it. Also had a nitrate problem, undergravel gone nitrate problem all gone too. High nitrates and bba get along well.

flesxruoyxllik 11-08-2012 10:41 PM

nitrates are high like unsafe high ive been working on that with weekly water changes
i cut my photo period to 6 1/2 hours
picked up a big bottle of excel im going to start dosing as soon as nitrates drop

i think if you don't get rid of the ugf you will always fight nitrates.. They are hard to keep clean. Too much sludge gets into the substrate which is difficult to keep clean with plants.. Many years ago I had a ugf and I could see from under the tank. I was able to put a thin, maybe 1/2", hose down the lift tubes and move it around to clean the junk from underneath. Had to do it often. I say, pull the tank apart, replant without the ugf.. Its a pain one time.. the ugf will be a pain for a long time..

Nothing inherently wrong with a UG filtration system and higher nitrate production for a planted tank. Get some nice root feeders and heavily plant the tank, keep up with water changes. UGF's are ineffective for very large bioloads in non planted tanks, but are perfectly acceptable in planted situations or for shrimp tanks. Just my two cents on that, not a huge fan of them but it's not the end of the world.
