MH is hot, uses lots of electricity $ and it need replacement yearly. Try LED, it may be expensive initially but long run it is cheaper.

Usually it is cost by dirty pump impeller. Try removing them and clean them. It may just solve your problem.

I am using the aquaPro Z Led for my blue night light too... My tank is 2 ft deep... Good enough

I think the Zeovite have not really perform to what it claim. That why many people have given up using them including myself.

That why you need a auto water top up setup too... To keep the water level constant.

Resun is a reliable china brand. I have many friend with good experience with them including myself.

I am using a 50gph r/o for my 5 ft tank. It is good for water change but when I setup the tank it took me two day to collect enough water for the tank. My TDS at output read zero.

I am using an eheim pump. My is very quiet maybe u shld try cleaning the pump.

Good explanation.... I am using a CR... It is a bit difficult to control the balance at first but with try and error it will work.

I using eheim 1260 but it have two outlet... I control my flow rate to the chiller...

I buy my from c328

I think ur flow rate too fast...

U have to cut ur ceiling board and place a piece of wood on ur false ceiling then hang ur light using the wood as anchor. Remember to put the cut out ceiling board and buy the ceiling filler to restore ur ceiling to its original look.

I have used a resun for 3 years... Still running and cooling... Just have to clean the filter often.
