Sorry mate, just thinking about the actual tank, my fault for being lazy. I have in full-RO unit, 2 powerheads, 1 skimmer, return pump, phosphate reactor(using rowaphos) and pump, flouresent lights( 3 powerglo marine 30 watt, 1 blue), 40 kg of LR, refractometer and gravel which i am going to change to sand. The flow on the powerheads comes to 6400LPH. I have 2 heaters left from when it was a FW tank and 2 thermometers. I am going to get a new water test kit though and also thinking of investing in an electrical ph tester. Have purchased 25kg of salt the other day. Including this and the cost have having my tank drilled , buying the sump and altering my cabinet has cost me £1455. I am brassick, don't think i will be able to afford to eat for the next few weeks. Sorry for that mate, if you can think of anything that i cn't it will be greatly appreciated. Thankyou.
