Does anybody know of a way to tell the difference between a collonista snail and a sundial snail? I have been staring at the on-line photos and comparing them to the snails I am pulling from my tank. I can't determine which they are.

Anybody know of a reputable non-profit reef preservation group? I can find several with online searches. I am just wondering if anyone has experience with any of them.

I have had a 30g FOWLR going since Sept--all is going great thanks to the info & advice I have found on this site. I actually paid attention to the temperature during my last PWC. It went from 77.4 at the start to 72.2 when I was done. I am sure the PWC process puts some stress on the...

There other day when I turn on the lights what appeared to be 6-10 flesh colored tadpole type things dropped from the surface. They were maybe a 1/8 to 1/4 inch, round, with little tenticles/flippers/tails. The cylindricus and lelupi ate them all in about a minute. I addition to the...

Do colonial hydroids retract like feather dusters? I have a small group of something growing. They look more like the pictures of hydroids I find on searches, but retract into the tubes like feature dusters. No photo - I can't zoom on them with any success.

30g w/ 45# of live rock. I got the rock from an established tank 5 days ago. There is coraline everywhere, some puffy flowing algae and all sort of creppy crawlies moving around. Ammonia held around .25 for a few days and is down a little. I threw a raw shrimp in when I put the rock it and...

Tank is full. Readings are all zero and sg looks good. I have the following equipment hooked up: AquaC Remora 800, Hydor 600, heater. I also have a Fluval cannister filter available, but would that be overkill on a 30g? I am hoping to pick up some live rock next week, if the person selling...

I am new here. I would like to get back to saltwater. Currently I have 180g with tang cichlids, 75g fresh, 30g (was brackish, but puffer just died), and 10g empty. Given that the 30g is now available I was looking for opinion on starting this as FOWLR tank? Due to some remodelling at home...
