Excel & CO2

If you are using pressurized CO2, can you use Excel/Metricide along with it at normal dosage? Are there any benefits/disadvantages in doing this? Is it harmful to the livestock to use both?

I use both co2 and excel on my dirted tank. right now I am using normal dosage, maybe a bit heavy. I was hitting excel hard for a bit to knock back some algae.
I don't think I really need the excel due to the co2 but it doesn't seem to hurt. livestock are happy. I did murder the entire tank when I hammered them with too much co2. I learned my lesson. ( I suppose those neons learned my lesson also)

I was using Excel/Metricide before I swapped over to pressurized CO2....stopped using it since. I keep reading where it deters algae, & that's what made me wonder if both could be used simultaneously.

I run metricide and co2, IMO It helps keep algae in check.

When you guys are using it for algae control, are you just putting it in the tank, or spot treating the algae directly?

Either or. Spot treat if you have some like the noob suggested, just regular dose in the tank if you have no problem areas.

Adding it to the tank is ineffective against already established algae, correct?

I double dose excel everyday with my diy c02. Never had a problem. It definitely helps with algae.

Excel or Metricide will kill most algae if it is in contact with it at a high enough concentration, and it is pretty hard on algae even when diluted in the tank water. The primary reason for daily dosing it is to provide a source of bioavailable carbon for the plants. Its effect on algae is a secondary benefit.

Now that I'm running pressurized co2, I'm going to start dosing the Metricide again.....for both benefits that @Hoppy stated.

I dose 20 ml of metricide morning and evening in my 29 gallon. I also have pressurized CO2 running at ~3bps. I don't spot treat - just dose the whole tank.

Sorry, Just saw this. Very well. It actually seems to be keeping the BBA at bay. The fish don't seem to mind at all, plants are healthy. I do seem to have fewer snails than I used to, but I'd consider that a feature, not a problem.
