August 6, 200620 yr comment_114470 Hey all setting up a marine reef tank. any comments on the physical placing of the bulkhead fittings as indicated here . Bottom would be take off and some sort of switching device to alternate the return to the above bulkheads. Planning to have some sort of directional control on the return bulkheads to deflect/direct flow. Any ideas coment would be appreciated. More plans to follow but keen to get the tank drilled and home while the rest is planned like pumps etc. Chrs Report
August 6, 200620 yr comment_114471 What made you decide to go for closed loops over powerheads? Report
August 6, 200620 yr comment_114489 I don't think that was his question. Safety wise those positions are fine, not too close to the edge is the important part as the glass can lose strength. Mine are very similar positioning to that although are more in a line about 150mm in from the back. Before you proceed though, I would design the aquascaping first and the closed loop around that.

August 6, 200620 yr comment_114493 Agreed Chim, that centre front one will be awkward to hide? Report
August 6, 200620 yr Author comment_114498 Plan on power heads as well. I have two old aqua clear 802's. Trying to think ahead and get extra's done now ... even if I blank it off and dont use it for now. Reckon easier than drilling down the line when tank is in use. Keen to do both to get good water flow coverage. Overflow on the right two stand pipes also 40 mm. Going to give the durso type a go. Chrs Report
August 6, 200620 yr Author comment_114501 Thanks.. yep Chimera, good point on the centre one.. Did not want it too low to suck up lots of gunk. Aquascaping? .. dont I dump the rock in? Then fiddle for months after that? Not had a great deal of thought about the aquascaping other than thin sand and rock in the middle. Floor 1500 x 600. Report
August 6, 200620 yr comment_114544 If you haven't already, double check the required drill hole size for the 40mm fitting because its quite a bit bigger, by getting one or asking Report
August 6, 200620 yr comment_114569 From memory I used 40mm for 32mm bulkheads, but I did have to hone them out a little bit to get the fitting to go in. If you can you should buy the bulkheads before the tank is drilled them you can take them to the tank maker and get him to make a hole to fit. Report
August 6, 200620 yr Author comment_114584 Thanks, you guys have probably saved me some dremel work.. Was going to work of these dimension but will get fittings first. http://www.hansenproducts.co.nz/tech/thread/dimensions/sftft.htm#SFTF Chrs Report
