Bubbles on EVERYTHING!!!

[Fishward]

The sump was a bit low when i came home, but only a powerhead was partially uncovered. the water is still perfectly clear, no bubles suspended, only attached to everything in the tank!

Could be the start of Cyano. Do you notice any red slimy algae covering the substrate? How old is your system?

[Ron99]

A nutrient issue leading to bacterial growth? i believe bubbles on the rock are usually from bacteria such as cyano or from dinoflagelates.

there is a brownish hair algea type stuff growing. not forming like previous cyano i've had. my tank is about 2 months old now. but i started it from a previous tank about a year before. upgraded from 30 to 65 with a 30gal sump. anything i can do to curb it? slow feeding a bit? fewer light hours? i have a tang and an angel grazing.. 6 snails and a hermit. good population of brittle stars and bristle worms so i dont think overfeeding could be a problem...

Sounds like dinos.

[Ron99]

BTW, are you using RO/DI water? Silicates in tap water can promote the growth of dinos.

[Fishward]

i do use RO/DI water but i've never had a TDS to measure exaclty how good it is.. bought the unit used and put in new filters. any good ways to eliminate it? same as all algea? lights or nutrients?

[Fishward]

just looked up some photos of dinoflagelates.. im pretty sure you're bang on. :-( is it manageable?

[ScubaSteve]

Dinos! Had the same thing. Best way to curb that now is to switch to good RO/DI and make sure that you aren't introducing too much O2 into the water, like an exposed powerhead when the water is low. When my watergets low, just the extra agitation from the water falling farther can bring on a dino flare-up. God... I make it sound like herpes...
