DIY Algae scrubber

[Angelphish]

Guys i have a couple of questions about seachem denitrate. I figure since i have the algae scrubber running on one tank i'd like to set up a denitrate filter on the other tank and compare the two.

Wanted to run this by you guys and ask some questions.

Couldnt i fill a spare eheim 2217 with denitrate and run a 30 to 50 gph pump on the inlet (bottom hose) and place the return hose in the sump work ?

Could filling a jar with denitrate and running an air pump through it work ?

Angelphish mentioned 6gph but everything i read says under 50.

How much denitrate would i need to treat a 300 gal tank ?

The info I read on gph was incorrect. It can be up to 50gph. 30gph is what I plan to run it at.

You can use the spare eheim with the lower gph pump, it just wouldn't support aerobic bacteria in the anaerobic environment.

You can't use an air pump with denitrate, as the bacteria is anaerobic. Having an oxygen rich environment would prevent the bacteria from growing.

I just got my 6th liter of denitrate, along with 30 vials of biodigest. I plan to introduce the bacteria to my smaller tanks first, as I haven't completed the filter for the 210.

So the anaerobic bb wojld be fine in the eheim right ? Totally forgot about the air

Yes, as long as the flow is low.

Added another test tank,
My 30 gallon fry tank is now self contained, with only a 49 square inch screen and powered with about 20 watts led. As its only bio filter.

Doing that right now. Still on hold cause of some stuff going on at home. Using a small jabeo pump with this. You'll need about 3-4liters. View attachment 1238357

I made a net screen, added all the algae from my last scrubber harvest. This should green up in a week. Then maybe I will be able to blow threw the 25 ppm nitrate in this 30 gallon tank.View attachment 1237988

I also added 24" algea/moss river. I will see how it does, as the screen greens up.View attachment 1237989

Day 2 or about 60 hours at 300 watts.
Once the screen is full grown, I will cut back the time. Test other lights. As I refill the tank with used aquarium water.
Nitrate was apx. 25ppm
today it is apx. 10ppm.
The algae is very yellowish, short hair algea.. I am adding iron also.
