decipher the question:
a 10 gallon with a hagen 402 pumping water in and a 402 pumping out.in the 10 will be caulerpera and miracle mud with some lr.or a cheap canister filter with out media and but in caulerpera and miracle mud.but im confused how to light to canister(if i need to)
You have a 10 gallon glass tank. You want to place a Hagen 402 powerhead in the main tank and pump water into this 10 gallon tank.
In this 10 gallon tank you plan to have another Hagen 402 pumping water out back into the main display tank.
THIS WILL NOT WORK as mentioned.
An overflow or gravity return will.
Continuing on:
You plan to have miricle mud, Caulerpa macro algae and some small pieces of live rock - for nutrient export.
THIS IS AN EXCELLENT IDEA.
OR you want to use a cheap canister filter without any media intalled in it, for pumping and returning the water from the refugium, and you want to place this canister down in the 10 gallon tank with the mud and rock ?????
And you want to know how to light the whole thing ????
I'm trying here joe .... work with us - please explain
