Thanks Geo57. No worries on taking a few days to reply. We all have lives to live!!
I got inert sand the other day in the shop and gave the coral sand to a fella I know who keeps cichlids. Ive also packed away the wave maker.
My new tank arrived 2 days ago so been busy getting it ready for bringing into the house. Its a Jewel Rio 450L tank. It has an internal filter and I was going to run it along with my 2 canister filters but can only fit the pipes from 1 into tank so Ill just run the internal and 1 external. Really looking forward to getting it up and running.
Just out of interest what sort of money are discus in the USA?? Here in the UK Ill be paying anything from £30 - £120 ($40-$165) for 3.5 inch fish.
