plantbrain GW you cannot water change away, there's a chemical method, but a UV run for 3-4 days is wiser.

It'll likely never bother you again.

So borrow a UV is possible or buy a cheapy and then resell it later.

Kathyy It seems like more nitrate than you need but the others seem fine to me.

Perhaps the theraP created an ammonia spike that set off the green water?

Once started GW can be a beast to get rid of. If I just allowed floaters to cover the tank it would eventually clear up as they both are efficient nitrogen removers and shade the tank. I haven't [knocking on wood and crossing every finger and toe] had GW since installing better biological filtration in the sump, giant sponges.

AJ12 Ok so im turning the co2 and the lights off for the next few days and im suspending the fert dosing. As far as the amounts of fertilizers doe that sound like it may be too much? Im sure after having the lights off and another 80 gallon water change the tank should have cleared up, i just dont want the green water to come back.

h0meless If your plants aren't getting any light, I would assume they won't be using any of the ferts since photosynthesis would be limited. I would also imagine that the co2 would need to be turned off as well since your plants won't be using it without the light.

AJ12 I'm using a full co2 injection system, I'm just adding excel on top of it to help with the algae. I do have a gh buffer I'm just using up the equilibrium first. Today out of frustration I shut off the lights and don't plan on turning them on again till Monday. Should I suspend my fert dosing for a little bit?

Darkblade48 I do not have experience with the light fixtures you are currently using, but it seems like a lot of light to me.

Regarding your dosing, you may want to look into using a GH booster instead of Seachem Equilibrium to buffer your water, since it will be economically more viable.

As for your situation, a UV sterilizer is a good way to (eventually) get rid of the green water. You can also try a 3-4 day (complete) black out, and it should eliminate the algae.

I noticed that you are not injecting CO2 and are only using Excel; in an aquarium this size, using Excel will become very expensive, and I would recommend that you switch over to pressurized CO2 instead.

AJ12 I also started dosing Microlifts TheraP about three weeks ago, could this be whats causing such a green tank?

150g EI dosing help

I have a 150 gallon high light tank running co2 with four 36" Fluval plant LED's and two 72" VHO's. Ive been dosing 2 3/4 tsp of kno3 and 3/4 tsp kh3po4 on macro days and 3/4 tsp plantes on micro days. I was recommended to use these amounts and do a 80 gallon water change once a week. I only use RODI water that i buffer up to a PH of 6.8 and add 3 tsp of seachem equilibrium for all 80 gallons. My tank looks like pea soup right now. Is this too much ferts for this size tank? I also started dosing seachem excel to try and help with the algae. All my plants are doing very well its just the green water is killing me. Im also running an 18 watt UV which i thought would help with the water clearity. Any thoughts?
