cheers suphew
i realised the co2 aint much good a little while back - i have parts for a diy reactor coming soon (i hope)
And just yesterday i replaced the old tubes and bought another tube so have 90W in total (low still i know but with a 4 foot total length 120W is the max i can cram in - is this true?)
i am feeding a range of rinsed bloodworm, rinsed discus tucker, flake (<1.5% PO4), colourbits (<1.5%), and greens (can't remember the name i'm at work). The amount is now so small, that all is consumed now in under two minutes and with clown loaches hovering underneath, i'm hoping leftover and waste is negligable. Still, i will do as you suggest, stop feeding to try and eliminate that side of things.
i have added a fertilizer but there aren't any phosphates listed.
Nothing added to the substrate. It is plain old river gravel about 13 months old from the lfs. I wouldn't have thought it would break down and leach phosphates????
I'm happy to buy a bag of phos-sorb if it'll fit into the eheim 2215 and other methods don't help....
Once again thanks for your advice :lol:
