I am thinking about this also. I think the best option (not the cheapest) would be an electrical float switch that would activate a solonoid for the sutoff. This would work for a sump. You could also incorporate a pressure switch in conjunction with the solonoid. This would allow the valve to...

Building an internal overflow for my tank. I have a IWAKI MD70 pump about 9' below the top of my tank - 1-1/4" line. Not sure what my actual GPH will be - But I want to get the overflow right the 1st time. Planning on a corner unit 4"x6". What size slots are needed in the top of it and how...

Just ordered a CS6-2 and am designing my sump for it. What is the optimal water level for it? I wish the Euro-Reef website had the information AquaC has. By-the-way. You can never have too much skimmer right? I have a 55 gal with 29 gal sump/refuge. I aught to be able to handle a pretty good...

I have a 55 gal that I want to keep hard and soft corals in. I think I will have two 40W Actinics and two 175W MH. Which bulb is considered the best for this setup? Would two 110W VHO's actinic's and two 175W MH be too much? Can I get the job done with VHO's only - 2 pairs. Actinic and full...

Do the Cartriges and membranes in the RO/DI units neet to be replaced based on time AND/OR gallons? For example, If I get a RO/DI and just use it 20 gal/month, will I get the same gallons out of a set of filters as I would if I used 300 gal/month?

Looking into investing in one these myself. ame across a possible alternitive. What about the "Tap Water Filter" that makes DI water at about 10 gal/hour? It is just $30. Replacement filters are $17 Sounds alot better than $220 for a Hi-S RO/DI system. What am I giving up? It is better than...

I hear you on the copper - I had always had it in the back of my mind. But right now, the Rocks are still in the freshwater tank. I will remove the copper in the morning. Should have used zip-ties anyway. I should probably test the freswater for copper and modify my decision accordingly. Any...

Excellent point!

I do have 2 or 3 small peices of copper telephone wire holding Java Fern onto the rocks. What are the chances of this effecting things in my size system?

I thought that I read somewhere that the PC's were cooler. Is it the bulbs themselves, or is the heat in the ballast? I am gathering equipment for my 55 reef and was leaning towards pc's. Had thoughts of puting a 175W MH on one end - for variable conditions. Would rather stay away from the MH...

Can that plankton in any way be self-sufficient with a tank and refug setup? Will it reproduce on its own?

Why are they dreaded? Whay type are they?

Just setting up a 55 reef with 29 refug and Iwaki MD-70 pump. Which is quite large for this setup - i think. will cutting it back introduce more heat, or what? I think the minimum flow on their website was quite low. Will have the refuge about 10' below the water level in the 55

I have many lbs of "honeycomb reef rock in a ciclid tank that I am going to convert to a reef tank. There are many excellent pieces of rock in this tank that I would like to incoporate as base rock in the new tank. I have never used rock that was this established in freshwater (over 10 years)...
