After a year or so, I have finally installed a sump for my TL 550.
I will post pics of the modification soon.
I have drilled a 32mm hole into the back of the tank for the overflow and a 20mm hole for the return. The back of the TL 550 is glass not acrylic so I had to source the drill bits. Builder warehouse have got in diamond drill bits from Torkcraft. I paid R129 for the 20mm bit and R169 for the 32mm bit.
Drilling was a breeze, but I did quite a bit of practise before hand on old glass.
The overflow, will start to operate from tonight. I have split the overflow into the sump into two lines. One line will run over an ATS and the other will flow directly into the chamber of the return pump.
I have set up a DSB underneath the ATS in the main chamber. The sand is playsand at a depth of appox 12cm. On top of this I want to put in Chaeto and some other macro algae.
The return pump is 2000L/hr, I dont know if this is too much for the tank. Advise will be appreciated.
I still need to install some lights in the sump for the ATS and for the algae growth.
Space is limited so I am going to put 2x50w downlights for the sump and try and squeeze in a 23W CFL floodlight for the ATS. I hope this is suffiicent or is it overkill?
After all of this, if I still have space, I want to chuck the Boyu skimmer as far as I can throw it and put in a lekker skimmer in the sump. Any advise here would also be appreciated.
Here is a pic of the sump. It is approximately 60L.
