Nice sump Borderjumper. That is pretty much the same design I have been considering. Are the baffles glass or acrylic? I know that silicone does not bond acrylic to glass as well as using all glass but acrylic is much easier to cut for a DIYer. I have been trying to decide whether to use glass or acrylic for the baffles. I hope I am not high jacking the original thread but just wanted to ask about the pros and cons of glass versus acrylic baffles when using a glass aquarium for the sump.

We used acrylic. Its cut so it fits fairly tight. I would never try to make an all acrylic tank with silicone, as Ive read it doesnt bond well to acrylic. For this use it worked just fine. Notice we siliconed along both sides of the baffles.. so even if for some reason the bond failed on the plexy.. the silicone bead on the glass would still hold the baffle in place. You have to get pretty creative siliconing the center baffle on the bubble trap. We used a long chop-stick to get the silicone down in there.

The plexi was about 40$. That was for the 4 pieces cut to the correct size. We made the "teeth" on the refugium baffle. This was a PITA. Im sure it would spill over just fine without the teeth.

One more question for you Borderjumper. What did you use to cut the acrylic? I will be using a table saw so I need some kind of 10 inch blade. I have done a search on this web site and others and most recommend using an acrylic or plastic cutting blade. I will not be doing enough acrylic cutting to justify spending $60.00 to $100.00 on a blade so I was wondering if a standard wood blade with fairly fine teeth would work?

ive used a band saw with fine teeth and a table saw with fine teeth with success.

We had the pieces cut to size at the place we bought the acrylic. Make sure when you measure you take into account the thickness of the glass if you measure from the outside.

Its a royal pain to have to cut down an 1/4of an inch on 4 pieces of acrylic.

A tablesaw will work..we used the blade that was on there..
EYE PROTECTION!
dont expect an exact cut and there will be some chipping.

Thanks for the info. I picked up a 200 tooth 10" blade at Home Depot. The blade is for OSB and plywood but it also says it can be used to cut plastics and the best part is it was only 16 bucks plus tax. I am going to try cutting the acrylic with this blade on my table saw in the next few days when I have some free time.

It should work ok.. my husband cussed the whole time he was sawing ours

Wear long sleeves as it throws out tiny shards of SHARP shards. And protect your eyes. Lemme know how it goes. Cheers.. Shelley

how noisey is that sump you made?? because i have my tank in my livingroom

The sump itself is quiet, as we have the drains terminating partially submurged with just a little air space at the top so it doesnt "glug".. now mind you, we dont have the skimmer in yet.
There is some noise at the display from the overflow pipe.
