Flow rate and pH

Hello again!

What's a good flow rate for a S. bandensis tank? We have a pretty low flow rate through our tank and we want to bump it up because we're having a nasty dinoflagellate bloom (ARGH) and we want to increase the flow (which is supposed to help fight those slimy little bastards).

Also, the pH in our cuttle tank is about 8.3, and another way to get rid of dinos is to up the pH to 8.5 (slowly, of course). Will that do any harm to our cuttles?

They can take a lot of flow, but so can dinoflagellates. To fight dinos, try a large water change, siphon out the dinos and vac your sand, turn you lights off for 3 or 4 days (any animals you have should be fine), and fun carbon. I have never found upping the pH to do anything to dinos and would suspect that raising pH by .2 would be so small as not to have an effect on anything. Good luck!
