I have had several sumps over the years. In The last year I had a Tideline and bashsea sump both Leaked within a few days despite having leaked tested both of them. The acrylic panels were NOT properly glued in in the Bashsea fuge sump. The tideline LEAKED from the Back seam. Thankfully the dealer i deal with graciously refunded my money and was angry that he had sold med sumps that despite Good{relative} reputations they LEAKED, What was the chances, Crap happens. Anyway For months i dabbled with ideas and then I always had in the back of my mind Icecap. They were solid sumps BUT I did NOT like the Ato sump design. I felt it was WASTED sumps space better used as a reactor space or refugium. So i bought the 36 inch model. After much Thought I derilled out a 2 inch hole into the ato area between the sump space and wall of the ato. Now I have a fuge area and /or a reactor space the idea works perfectly . Just throwing the idea Out there for fellow icecap owners. My sump now WORKS FLawlessly and Icecap makes admirable sumps. Done with Bashsea and tideline IMO they cannot compare with the quality of Icecap made sumps. By the way had 3 bashsea sumps over the years so last one was POORLY made, Consider Icecap best buy I personally made in the LAST 2 years, Cheers!
