Am posting some pictures. In February we bought a used 210 gal
, 75gal sump set-up and replaced our 75gal. The sump is really too big for the cabinet and cannot be removed without breaking the whole thing down. The protein skimmer is the same way. We had our local lf guy do the move and I don't know anything about the skimmer except to empty and clean the top part. I am having water problems because I have an algae outbreak that is getting worse instead of better. I use RO
water and am changing out about 25gal every 5 days. Nitrates and phosphates test very low to none but of course that could be the algae. I am feeding 3 times a week. Look at the pictures and see if you have any suggestions. I've tried chempur and put a filter sock over the input to the sump. Any suggestion appreciated.
