🧪 Denitrate - 4 Liters / 1 Gallon Review

I have many freshwater and saltwater tanks. I always use this product in each of them. But this is Seachem, so what can you expect other than awesome?

Once I started using this conscientiously in my 75 gallon tank I was able to keep nitrate at reasonable levels to control. I just put it next to the charcoal and ammonia backpacks. I don't have a high bitrate filter, which I think helps.

I will retest my nitrates just to be sure. I want to start with my 300 gallon pond filtered and full of pothos. I bought this because I was still struggling with 80ppm nitrates with my goldfish (think they're dirty). I bought these and realized they can't be in a high flow filter (it sucks, huh?).

He went to 120 gallons and basically added about 60 gallons of new RODI water after we drained some water and the reading went up from the graph to about 120ppm so basically nothing was working…

This product is very effective, but Seachem does not document well what makes it successful. It's only on their forums and not every piece of advice in one post, they're all scattered around. I've used these tips in three different aquariums and they always work. Use 4-5 times more than Seachem's directions if you have high PPM. You MUST use a slow flow of 20-40 gph, 25-35 gph is the sweet spot. I use a large media reactor from Avast that holds 4 liters and in front of it a more than…
