Cyanobacteria.... question!?

[underWoasisjake]

Ok i have been reading some threads and some have said that cyano is bad and to take it out of my HOB fuge..... other threads have said to leave it in because it is eating up nitrates and phospates and to let the algae grow in the fuge??

I am lost now is cyano (dark red algae) good for my HOB fuge and my 125 reef in general or should i take it out? Also i have noticed my nitrates starting to increase.... i have cut down on feeding!

Should i aslo take off my fluval 304???? or should i replace the media in there with live rock rubble and some nitrates sponge??

Suggestions and info would help thanks alot

Let me ask you a question, if the macros where not doing well in the fuge, would you expect the NO3 to go up or down?

also, if the macro's where not doing well in the fuge, not cleans ans fluffed periodically, would expect other noxious species to appear?

If you use a fuge, focus on the needs of the macro's.
Often we can get away with several weeks, maybe months of good growth, export, then they grow, get bigger, and basically eat themselves out of house and home nutrient wise.

So prune and clean them regularly, keep the algae you want, not the ones you do not.

As you can see the Cyano does pretty poorly for NO3 removal, assuming the test kit is calibrated and accurate.
