More cheato/refuge questions

[albatross666]

Hi

 

I have some slimy red stuff that forms a thin layer like an oil slick on the top water level of my HOB refuge. This red slimy stuffs get all over my cheato.

 

Also, I am still fighting a winning battle against the brown slime/hair type algae in my main tank.

 

I have a red grape algae and cheato in addition to a 2 inch layer of sand and a few rocks in the refuge. My aptisia is practically gone (got a shrimp in the refuge).

 

I am using the provided powerhead with a small CPR HOB Aquafuge with the CPR light. Is this an indication of slow flow? What else could be wrong?

 

I am going to fiddle with my light cycle and reduce the light from 8 hours to 7 hours.

 

Thanks

I get a little of that red stuff in my fuge, also - I think it's probably cyanobacteria. Tends to form in the spots that get lower flow.

I have the same problem. When I had 192 watts of pc lighting over my 55 gallon fuge I had a real problem with cyano in my fuge with a slim on the top, but none in the main tank. Then I switched to 2- 23 watt flouresent spot lights and that ended the cyano in fuge. Now, I am fighting cyano in the main tank. :(

Better in the fuge than the DT....that's my motto!

On the CPR refugiums you can adjust the flow going through them right above the intake pump, perhaps you need to allow a little more water movement. I don't think your light cycle is this issue since I run my fuge with the same light for close to 10 hours and I have had no such problem.

I have a DIY HOB fuge based on the CPR design (just larger :-) ) 36"x18" 5" and yes, the cyno is because of a slow flow within the fuge. I solved mine by the flowwing; 1)remembering the thin the cheto more often 2) I added a powerhead inside the large compartment of the fuge to increase flow. Too much water into the fuge from the return pump/display tank tends to raise the waterline too much but adding flow, by using a powerhead increases water circulation without causing water to spill over the side.
