AB,
I am looking at 1800 S2. Few questions?
1. Is back of tank that contains auto top off is all glass or acrylic in front. I don’t want acrylic as easy to scratch when cleaning algae.
2. I heard about overflow noise issue with overflow in S1. Is that fixed in S2?
3. I want to add 7” Klir filters (1 for now and maybe 2nd one later). Can i have two 7” filter socks instead if four 4” filter socks. Can the
4. Is there baffel to keep 8” or 9” height in skimmer chamber. I want to use skimmer before refugium chamber, can the divider can be adjusted accordingly as well?.
1. the tank is 100% glass minus the lid for the ato, and the lids for the return and drain. I suppose if you are including the jump net in the word "tank" then the jump net is not glass.
2. the complaints that you might see about overflow noise in the S1 I'm not sure what that is about, but in the S2 if the valve is adjusted correctly on the drain then there will be ZERO noise.
3. you can do the 7" klir, but you will need to make a slight modification to the sump which I can provide instructions (from the manufacturer) on.
4. I can ask about running it higher, but I am pretty sure that would effect the way the water flows over the socks from the return pipes and effect the overall noise and functionality. Can I ask why you would want to run 8-9" skimmer chamber height? And what skimmer are you trying to use?
