pressurized co2 w/ drop check
Inert white sand
25x root medic tabs
16 pumps root medic macro; (4x wk)
16 pumps root medic macro; (2x wk)
Heavily planted
8hrs light/day

Before the ferts, the water was clear for several months. But the plants were not growing very well. Once the ferts started, it was great for a while.. The plant are growing like mad.

But now, daily water changes won't keep the water clear. I stopped fert & turned lights off for a week. Didn't work. Lights and ferts schedule are now back to normal.

Last water change was Saturday, tonights params are 0ammo, 0nitrites, 20ppm nitrate, 0phosphate.

An appropriately sized UV sterilizer will kill the green water. By the way, you need 1 to 2 ppm Phosphate.

I'm trying to avoid the UV this time... I want to solve the problem naturally.

I know I need 1ppm+ phosphate. That was what I was hunting with the heavy ferts. I had to put in 16x squirts 5x week to read 1ppm phosphate.

Could it be the nitrate that's feeding the algae? With higher phosphate the plants could eat more nitrate. Could adding more nutrients kill the algae?

It's not the money; I'd just like to understand what's causing it.

ok to start.. good circulation is KEY here. green water likes to be stagnant.. it hates to be moved

I'd try a more stable fertilizer routine.. high fert levels don't cause green water..
what's ur ammonia at? ammonia easily causes algae
high lumens without good par grows algae.. this is true for when bulbs lose theire spectrum. plants grow fast under high light but grow bushy and healthy under high par.

how old are your bulbs?


edit: i noticed u posted 0 ammo.. so cancel that.. back to daily routine then on ferts.. parameters might be changing a lot

I wouldn't say I have good circulation. I'm not sure how to get the bushy plants from flopping and twisting all over when I increase circulation.

My lights are old, maybe 2yrs. All are 6500k.

Neither of those changed recently, that was true on "day one" 5months ago. (Not arguing that I shouldnt fix these issues though.). Just can't imagine they would be a direct cause.

stems will stop flopping if u trim them and install circulation. they will grow in a little more rigid to compensate.
there is a limit to how much they will.. if u have direct force on them, there is nothing u can do, but a wide current they will grow accustomed to easily

green water IMO is attributed to something with the bacterial cycle in most cases.. i would try increasing circulation before u buy a uv and do a good fertilizer routine over the next two weeks and see what happens

also increase surface agitation or aeration by either bubble stone or pointing a circulation pump upwards a little. this is beneficial to bacteria and plant health and helps water turnover

EDIT: i have a uv which i bought thinking it would be a good idea. i've never needed it, even when i started getting rgeen water 3 weeks ago, it went away on its own. i have high circulation and excellent surface agitation. my biggest cause was an overfull filter floss media tray. replaced with clean floss, and adter bacteria grew in. everythign went away

I do not recommend doing this but as a last resort it will work. You can get API's algae killer stuff (forget the name) and then after a day or two do a big water change and then do another a couple days after that one and it will be cleared up. I don't like putting chemicals into my tanks but as a last resort it will work. I do prefer a UV though. Good luck with the green water. From my experience it is really hard to solve but once I got rid of it by using a UV it never came back.

Sounds like a good idea. I'll increase water circulation and see what it gets me.

Why would it clear up?

You have 4 T5HO 54 watt bulbs lighting that tank. Unless you have very poor reflectors, or have the light about 3 feet above the substrate, you have very high light, and that will cause any algae to grow very well. So, first you need to reduce the light a lot, then start getting rid of the green water algae. A 2-3 day total blackout, with no peeking, will kill off the algae, so it can be filtered out.
