Yourself.





Never listen to any of us. Read the advice given and pick what works best for you and your tank. If you can only mix 20g at a time then 20g it is. If doing 10g once a month doe snot fix the problem increase it a bit. If doing a sudden 40g WC your corals or fish look stressed cut back a little. The goal here is to rid your tank of excess nutrients or phosphates.

Again I'll say, increase yor flow to 30 times the water volume of the tank, add a Phosban reactor (they really are dirt cheap and since this is a recurring problem it will only help), water changes.

Is the Phosban reactor something that stays on the tank or is it used only when needed?

This is the best phos media but it's pricey. A great write up as well.

This is the cheapest and most respected reactor.

Good deal and another write up explaining how excess nutrients contribute to algae problems.

well I just ordered a seio 2600 and I hope it comes in soon, but in the mean time I put my rio 2500 in the tank that I was using to help me pump water out and in for my water changes. it is moving a ton more water I hope it takes care of the problem. I have a hair algee problem any recommendations?

Folks:

I am asking this for my own edification.

I understand that in the "salt water world" lighting is as important if not more important than filtration.

I do not understand why Roger is experiencing this problem with a wet/dry filtration system.

In my freshwater system the return water to the tank generates significant flow in the tank.

This is just a question but would not a pump with a larger output fix this problem assuming the biological and mechanical filtration is adequate?

Jones in a 90g tank I'd be pressing for about 3,000-3,500GPH or more for flow. Flow is very important in saltie tanks. A wet/dry for a 90g tank would not work if hooked up to a pump that could push 5,000GPH (giving extra for head losses). Also wet/dry filters can become a source of bane for saltie keepers if it is not regularly maintained. that's why you'll here more and more keepers referring to a sump (a place to add a skimmer out of sight) and a refugium (a place to grow unwanted algaes and such so as to use upt the nutrients). A sump or wet/dry is normally recommended to have a flow between 5-10 times the water volume whereas the tank should have 30-40 times turnover rate.

I believe that I understand.

In the "saltwater world" the flow required in the tank is so great that if the flow were returned through the sump the filtration would not be effective.
