    Let me be the first to congratulate you !

    I'd join those sumps with a big PVC pipe connector

    I would take the two inside panels out and then join them with a vertical brace on both the outside and inside brace should be like 20cm wide and 6mm thick glass should work this way you will not disrupt the natural flow of your sump with a pvc pipe.

    Kool about the tank is this Robbie's old tank?

    I think take the panels out aswell. Don't like hindering flow by pushing it through pipes. But if your flow over the sump isn't so bad it could be ok. Just have the pipe well below water level. Then you won't add to salt creep. But imo taking the panes out would be better. Depends on the dimensions of the tanks.

    Where Are the PICS??????


    I would link by drilling the sides and linking using a flexible type pipe.

    Joining the two 1.2 meters will result in broken tanks. Glass is too thin to be able to pick it up and move it around. Imagine a 2.4m tank with 8mm sides. Nope do not even go that route.

    50mm PVC pipe can handle up to 6000L/h water flow under gravity. Only limiting factor is where you use the 50mm as an overflow, the water coming over the side entering the pipe is then limited.

    What you can do is use PVC pipe and 2 elbows. Build a upside down U. Just ensure it is properly glued, first with silicone and later you can redo it with PVC Weld. Then at least you can change it if needed. Bottom open ends should be cut at 45 degree or more angle. So that the pipe cannot be blocked flat at the bottom.

    Drill little hole at highest point. 6mm, and attached airline or black irrigation tube. Use that to suck (with your mouth) the air out the pipe to start the siphon. Just tuck it in under water level where it will stay when in operation. (with the black pipe you will taste it :))

    Both sides you can use anything to make a small chamber around the PVC pipe. From small little glass fish tank, to a plastic milk bottle with top cut off. Your choice on pricing. I will first use the plastic bottle, and if everything works, then I will beautify it.

    No need to stagger the tanks with the one higher than the other. Water level will be almost level during operation.

    If you think one PVC pipe cannot do it, then use 2.

    For proof. Just ignore the filling of the tank.
    Check the bottom left of photo. See the white PVC brige between my olf sump and new sump. I had both sumps running like that from JAnuary to end of March.

    Here you can see a bit better the water entering new sump.

    Can see the thin black pipe just before the bend. What I done, because I got tired of the salty taste is to use a small 1500L/h powerhead with venturi. And attached the pipe onto that. So that the air is automatically suckled out and siphon never stops. The powerhead also helped to keep stuff in suspension around the skimmer.

    Just be sure that the 2 tanks are 100percent equally level on the same level if joining with pvc. They will crack if they are not. I know its happened to me twice. Flexable piping will be better provided there is enough space between the 2 tanks too close and it will squinch.

    Hey frans, why not just raise the one sump above the other and let it flow naturally from the one into the other? I would be worried about joining leading to stress on the glass?

    As Leslie said, even drilling and using bulkheads to connect them will be looking for trouble. Best option is to bridge them.

    Having one tank above the other is not likely due to height restrictions. Both 1.2 should be around 450mm high. That is 900 and with support and polistireen about 1m. And that is without access space to stick your hand in.

    Only other option, is to remove on short side of one tank, cut glass shorter by max 50mm, and build a flat overflow with short sides. Like a waterfall. Then have one tank 50mm higher than other with waterfall overflow dropping into second tank. Just watch out for the salt creep splashes and stirrer up sand beds.

    I will go with the 50mm PVC connections
