Is it ok to use 1/4 in plexiglas, purchased at Home Depot, to partition my sump ?

I know I can use glass or acrylic but plexiglas would be easier, cheaper, and quicker for me. But, I won't waste my time if I can't use it.

I used 1/8" plexi until it blew out due to the flow. I would think 1/4 or 3/8 would be fine. Use lots of silicone too.

Depends on what your sump is made of and how big the sump is. If the sump is made of glass, then it will be difficult to bond the plastic to the glass. If it is acrylic, plexiglas might work but it will be weak so size of the sump will be an issue. If it is only going to hold 10-15 gallons, you might be able to do it. If it were me, I wouldn't trust it. I know a bunch of people use it but it could break loose. For your application, baffles, not much to worry about but others create entire sumps out of the stuff.
The other option is to just go to HD and have them cut the baffles for you out of glass and then you only need to silicone the glass in place. HD can cut glass up to 1/64 of an inch so measure and get a close fit.
If it is acrylic, just find a plastic's shop and ask them for a couple of cast acrylic pieces cut to size.

I used a 60g long glass tank for my sump/refuge and used Plexiglass for the partition with no problems. Been there for over three years. Just use silicone and put a bead on both sides of the plastic. Use the thicker plastic, it won't bow from the weight of the water.

Thanks for the replies. I feel pretty confident now with this advice.

The sump is going to be an glass tank, 30 gal or less.

RedWinger, I built a sump out of a 20L and glass partitions. I even drilled a bulkhead in my refuge, so all of this is pretty easy.

I can give you a tip though. Anytime you have water flowing OVER a partition make sure that the partition is higher than the next one that it has to flow over.

Here is a crappy pic that I made.

Plexiglass is the same as Acrylic.(actually Plexiglass is the company and Acrylic is the product except for knockoff situations the plexiglass is the product(but it's still acrylic))
