What is the best way to lower phosphate and nitrate level?

I would try Gfo and some carbon, but I would also reduce your lighting from 12 hours to 8. I don't think it will do anything for the levels but it will certainly help with any algae.

I have reduced the hour of lighting down to 8 and also threw in some carbon. For the GFO reactor, can it be used without a sump?

it can be ran both hob or in sump heres a pic



basically a input from a small pump like a maxijet and output with ballvalve

Redsea NO3PO4X, drastic reduction. I started at half the dose they recommande and the effect on algae is very noticeable after a week. Need supplementation of coral food or they will starve.

It's 28 gallon tank so I'd change 28 gallons of water, just like that zero nitrates and phosphates. Adding media reactors to such a small tanks seems pretty silly IMO, way more trouble than it's worth.

Does anyone have experience with how much clams can reduce nitrate? Is it negligible?

Reduce feedings. Minimize frozen food.

Proper maintenance.

I have never had any of either in six years... Asides from new tank syndrome.

Gfo is a band aid to the problem. Control first, Gfo as assistant or pellets.

Interested to know this too. Keep in mind though, clams can have special requirements of their own.... Pests can bother them and some fish may too.
