Hey hows she going byyyyyyyyyyyyyyyyyyyyyyyy.
If yo are looking for a skimmer in the 50 gal range there are alot of them. However when you are looking at ta skimmer for a small tank that is great. But with a 50 gal tank I always tell people that why not just do 5 gal water changes per week. really you aren't making any more head way on a 50 gal. Having a skimmer is only prolonging the water changes and helps in the assistnace of taking out the extra nutrients in the tank until you can do a water change.
But I would go with some thing on a top brand. from MY Experience. And believe me I have it ask any one hence the title under my username. and being from ST John's my self and living on 131 white a way street My Father was in the Forces.
how much do you feed now
where is the tank at ( some of the POC skimmers are loud.)
PM me your number and I will tell you what I think and what you can go for ok.
