My fish only tank has been running for about 3 weeks with brand new plumbing and a brand new tmc reef 4000 return pump that was set to power number 6 and the gate valve tuned accordingly.
Last friday i noticed the water level in the weir dropped a couple of inches so turned the pump up to 7, yesterday that became 8 and today 9 wasnt quite enough and 10 just a touch too much.
The tank is a DD 900 reef pro and for those that dont know they have a fairly small return plumbing at just 20mm, ive taken the pump out and cleaned it and that made no difference but i doubted it would as the pump and tank are so new, ive even changed the pump for an identical one as i bought two at the time, nothing changed so im at a loss as to what the issue could be.
Only other thought is the return plumbing has got very dirty and causing a bit more of a flow restriction, i can of course take it all out and check and clean but something just occurred to me that might well be normal ( forgive me as this is my first tank with a sump) ....
My thought is there could be an initial build up inside the pipes that would need the systems return pump/gate valve to be adjusted in the first few weeks or months as the pipework gets a layer of gunk in it, ive no problem running out and buying a more expensive pump but the two ive got and tested are doing the same thing so it seems unlikely both are dying when one has literally been in the sump for 30 minutes
Any ideas??
