did you switch completely over to these now? I'm still considering doing the bio-pellets at some point as well but have read too many issues with people not slowly adding them to their tank. Looks like you've had some good results so far. Really interested to hear how it goes for you after another month or so.

Nice results Frank, I run a koralin denitrator and my nitrates and posphates are very low. My system is heavily stocked.

Nitrates are 4ppm, I can get it to zero but don't think my clam would be happy. Phosphate is .02.

It's a nice set and forget system, I ran it for 1.5 years so far.

I run bio pellets and I have never ever had p04 in my tank or nitrates' date=' they are always zero no matter how much food I feed the tank. Using the hanna meter to check p04 and the salifert for nitrates.[/quote']

 

What size tank? how much of the bio pellets do you run.

I ran 1000ml of biopellets in my system for about a year, couldn't really tell a difference either way if they were working or not. My system just doesnt really make very much phosphate... I stopped using GFO long ago and my system always is about 0.01-0.02. I'm curious how your system is able to accumulate SO much phosphate? What kind of skimmer are you running? What do you feed? Where did the rock from your system come from?
