Problems in my CRS tank

fishy80 · 19-10-2009, 11:27 PM

I have been using Magic soil for 1 year now. I am starting to experience a lot of Blue green algae in my tank. Its starting to cover up the moss. Is this because of the breakdown of the Magic soil? How do I solve this problem?

Info on your tank... Nil

How to guess what cause the algae 'boomz'? Some possiblilties includes, too much light, no snail/otto in tank, imbalance of nutrient control, ammonia/nitrate/nitrite (whatever it is.. high bio load), etc.

I don't know if this URL is reliable, but well, go take a read up and see if you find any good info

Hi Sorry,

Nitrate less than 5mg and no ferts added. 24 w in a 2 ft x 1 ft tank. Everything to the bare minimum.

Blue green algae grows when nitrate levels are too low. If you have plants, dose a bit of nitrates to bring up the levels.

how long did you on the lights? any idea whats your phostphates (po4) level? high level of phostphates may lead to algae boom.

Hi, I tested the phospates level, its very close to zero. At most 0.008. Lights are on for 6 hrs daily. its off for 2 hours in between. Only Spiky moss and Subwassertang in my CRS tank.

BGA is normally caused by excessive nutirents or low flow rate of water or too bright light .

You can do this . Black out your tank for 4 days and you will see your BGA turn brown and suck them up and your tank should be fine.

1 more thing . Is your tank exposed to sunlight?

I dun think the lights are too bright. I am using a 24 w for 2ft tank. I am using a Eheim 2211 for filtration. My tank is about 48litres. I might consider swapping the rainbar for a lily pipe. Initially, the BGA was on the soil and I tried blacking out for a week. After that the BGA disappeared from the soil, it went on the moss.

Just to add, I did a nitrate test. The nitrate is less than 5mg, very close to zero.

Could it be the temperature? Apart from lighting, does cooler water reduces algae growth? Anyway, do you hv any snails or ottos to eat up the algae? I didn't see any mention of that.
