My deltec skimmer impeller keeps getting jammed by calcium deposits in the tank. For some reason calcium levels are always dropping despite constantly high alk and mg levels, which results in me adding a lot of calcium to the tank very often. Anyone encountered similar issues and know how to resolve?

What did you try feeding them?

Hi everyone I have a problem. I bought a red feather star yesterday and was told it eats phytoplankton so I thought everything was going to be fine. Put the phytoplankton solution in but it didn't eat, and it didn't eat any of the frozen reef food with tiny bits of krill and vitamins either. Anyone has any experience in taking care of them?

Thanks guys! Went down today and they had a tiny one left, I got him (it's a male) and he is happily munching on sps at the moment. Hopefully they will have more next week to keep him company!

Hi Bros, I'm trying to get some orange spot filefish for breeding purposes. Plenty of SPS in my tank for them to munch on, but of course I would want to train them onto frozen food eventually using bleached acro frags. Does anyone know where I can find them?

Hi Everyone, I was a member under a different nickname some years back and now have returned to the hobby! There is a problem with my 100g SPS tank. Calcium levels can drop from 420-350mg/ml, and alkalinity level drops from 4.5-3.5meq/l in one day. This is worrying as I do not know the root cause and if I keep topping up the calcium and alkalinity levels so rapidly, it will kill my corals and my wallet. Some background info on the tank 3 acros around 4 inches high and 1 LPS duncan coral (quite big around 30 heads) Some hermit crabs, sea squirts and feather duster worms pH 8.3-8.4 Salinity 1.0265 temp 26.2-26.7 Nitrates 0 Phosphates <0.08 (my test kit shows very little deviation below this level) magnesium 1440 (alittle high I know) additives (ultra min fine food for sponges, phytogreen 10-15micrometer phytoplankton 1ml/day, polyplab polyp booster 1ml/day, ultra minS nutrition concentrate 1ml/day) I usually add the calcium and carbonate powder to the sump. Measurements in the main tank and sump have no deviation. Could anyone please advise?
