Fluctuating CO2 and algae problem

[Viper007]

try not to use sms language here.

regarding CO2, i realise i have a lot of algae growing, might be because of the fluctuating levels of CO2 in the tank. so do be prepared to experience fluctuating levels of CO2 and the consequences. maybe in your nano tank you might want to add an Oto and a few shrimps..

Hmmm, I don't think CO2 has much to do with algae is most likely your lighting.

actually almost all algae issue is due to CO2, assuming you have plenty of nutrient in your tank.

Oh is it? care to comment a little more?

Assuming, I'm having a heavily planted 2ft tank and running 96W of lights with heavy fish stock how many bubble count is recomended?

it will depend on what kind of plants you have in your tank and how often you leave the light on.

i think it is because algae is able to thrive in fluctuating levels of CO2, especially when the levels of CO2 is low. hwever when it is low your plants are not able to photosynthesize due to the lack of CO2, and thus algae grows?

correct me if i'm wrong.

So if the CO2 in my tank is increased, does it reduce the chance of having algae?

it is not whether it is high or low levels of CO2, but fluctuating levels of CO2 that will cause algae growth.

if you have a method of keeping levels of CO2 constant using CO2 tablets, i suppose you'll not have MUCH algae problems.

IC I see, anyway I'm not using DIY system. so my bubble count is constant during lghts on.

well that only true if you have no other limiting factor, I mean nutrient in the water. Focus on growing healthy plants and algae will stay away.

It is ok to have fluctuation as long as minimum level is stay at least 25-30ppm. In other world it is ok to fluctuate 30 to 70 ppm for example.

Use kH/pH table (assuming you don't have anything that altered water pH or kH). If you do, use drop checker. Make sure your CO2 ppm is around 30ppm.

My 2ft tank is powered by 2 x 55W = 110W, no algae problem beside green spot . Some say increase potassium will reduce green spot algae, I'm curently waiting to see the result

Gee thanks, do update on the effect of potassium towards green spot. I have this little problem too on green spot thou is not serious at all well I don't want to act when the tank is full of it.

usually green spot algae is sticking on the glass, that one can easily be clean. The problem is when the stick on the stones, it can't be clean, tooth brush can't totaly clean it.

Easy meh... I have to use a blade to scrape it off.. And can see a layer of green slime. Lucky, is not serious. As for my lily pipe that is a bit difficult to clean.

[Shadow]

Mine never been that bad, usually I just wipe use those white color filter wool during my weekly water change. Not easy to wipe but do able

You mean phosphate/phosphorus. Some GSA is alright. Makes stones look natural. GSA on the glass is like weekly maintenance. Credit card, toothbrush for the silicone area and also the ADA algae scraper for the back and hard to reach areas.

I don't like adding phosphate. Plants get big like on steroids which makes the tank look smaller.

Sorry always mixed between two

Does anyone try Borneo Sucker (Gastromyzon borneensis)? I found it quite effective against GSA on the rock . According to the website, they do like to eat algae on the rock (sorry the link below is in bahasa Indonesia )
