I'm looking for some ideas for a safety measure in case of power outage if I'm not home. Right now if I lose power my return pump start to back siphon. I use to have the pvc return pipe about 2" under the water line so as soon as air hit it it would stop the siphon. I had to add some more pvc so...

I run a Fluval 305 on one of my tanks pros easy to clean and can be done in a short time cons if you don't stay on top of them you open yourself up to Nitrate problems and that can lead to algae problems. I think canisters work very well on smaller tanks(under 100gals). Just remember you'll get...

A guy called me today, he has a 110gal reef tank 4'x30"x18" I think . The tank has been up for more then a year now and it has no coralline on the glass at all just a few places on a few rocks. I took my Cal Akl and Phosphate test over Cal was about 490 Alk was 8 dkh and he said the cal was...

I have 2 #4 and 2 moded maxi-jet in a 75gal. (I need alot of flow) and I'm not blowing thing over. I might move the top layer of sand in front middle every now a then but it's not much. The 2 #4's(on a wave maker) are on each end one mod in the back pushing down the glass and the other mod is on...

Originally Posted by Bang Guy I believe Plusrite is a distributor as well as a manufacturer. I am not certain but it looks like the OSRAM 400 20,000K MH is being distributed by Plusrite so that might be the bulb being sold. The PAR for 400 watt 20,000K bulbs varies from 50 (South Pacific...

Bump.

I was looking on ---- and I found a set of 400watt 20k bulbs for more then half of what I pay for my XM bulbs. Anybody have any insight on these bulbs? What is the differents in these bulbs and the ones I'm using now?

Originally Posted by Flower I don't know about anything "changing" but I agree that before is better...the quieter the surroundings after a new critter is added the better. +1 You want everything as settled as possible. I try to add thing at night just before the lights go out.

I use to think that SLF was one of the coolest critters you could have in your tank. About a year and half ago I went to my LFS and they had the biggest one I had ever seen about 7 or 8in across. The man couldn't get in the bag fast enough for me. I took it home added it to my reef tank and all...
