I would use a hang on skimmer before going with the gravity drain setup. I like to keep things simple and eliminate the odds of a flood or overflow....
If you have two small tanks as the sump/refugium/skimmer etc its best to tie them together with hard plumbing and bulkheads as its impossible to get...
Most pumps have a published pump curve which shows what it is capable of pumping at various head pressures of heights. You can usually figure 4 to 5...
Restricting a centrifugal pumps output does not harm it, in fact many times it improves the pump efficiency by adding head which is what you are...
You need to find out what ballast you have. With fluorescents (VHO,PC and T5)You can run lower wattage bulbs in a larger ballast but not the...
Sand sifters are not detritus eaters. They eat spaghetti worms, pods, etc.
Never never ever use tap water, did I say never? Start it right from the begining and you never have that nagging question in the back of your mind...
Sand sifting stars eat live foods not detritus and are a poor addition to a deep sand bed since they wipe out all the fauna. I know that from a bad...
When I had a 180G next to a window it was a mess. After it was moved across the room it was much easier to care for. Yes nutrient control is...
You won't want or need anywhere near 1600 GPH with a 75G display, plus the wattage is very high. Remember this pump will run 24/7/365 so stay as...
Definitely drill it if you know its not tempered, you may never get another chance.
I use mostly submerged pumps. Externals are normally less efficient in smaller sizes, meaning they draw more power per gallon of water pumped. They...
12 feet of head eliminates most common pumps as that is about their maximum lift at almost no flow. A Mag 12 or 18 will get you some flow but is not...
Doesn't matter. I used to hang mine outside the sump but switched to hanging inside the sump to save room under the stand. It works the same either...
Yamaharider nailed it. You never want to load a circuit to the max or you are asking for trouble. 75 to 80% of the rated amps is the recommended...
The filters in front of the membrane are under pressure. The DI is after the membrane and is at atmospherice pressure unless you have it hooked to a...
You only want like 60-100 GPH so any small powerhead will work. I use the MJ400's myself and they work great.
That is perfectly normal. If you raise or lower the line coming from the DI you will see the level in the canister go up and down. No big deal. The...
Seabass, I have been using the UPLC-II about 2 years now.
Spectrapure UPLC-II. Bulletproof with a three lobe peristaltic pump and an emergency back up float switch. Took about 1 minute to program and its...
