Ok everyone... it's been a long time for me, been really busy with work and the tanks. I had to do some reconstruction to my 20L that has been running for about a year and a hlaf now, not much in just yet really taking my time with it. I noticed a huge amount of what im thinking is pink sponge?? i had orange spong that came in on LR that i brought when i sent the tank up, but thats all gone (oh the joys of cycling!
). My question is, Is it safe??? , i didn't pull it out the tank when I was remodeling so there was no air contact, so i dont think its going to make the tank go crazy again.
Specs of the tank right now...
SG - 1.021
76-79 degrees
no nits nats or amo
40-45 lbs LR
40lbs LS
skimmer, fuge, blah blah blah LOL
saddle back, damsel, 2 PJs, orange spot goby, herms, snails
and I just added two small shroom
t5-HO double bulb 10K and blue ant.
powerhead and a hang on filter just in case.
Pink sponge? 
Please help ....... .... .. .. .
