with a new 9001 you will want to tune the water level to what works best with it... I ran the stock skimmer & to get it to perform, had to keep the water level window, at the top line & top off ever other day... keeping the water levels stable is key for all skimmers and that requires an ATO or adding water atleast every other day,,, hope this helps

. Thank you I did read all of what you said as well just dying to know about this sight window/glass. An ATO is next purchase just spent few hundred on upgrades and hanna checkers all that I need is LED lighting upgrade if not than a chiller but really want LED colors pop so much more with LED than T5 I think anyway and a ATO course those are $100 a whack too. Knew this wasn't a cheap hobby but damn.

if you don't have a "water level window on the left side..." you have the RSM 130 tank, the RSM 130D (deluxe) added the window... and the adjustable skimmer cup - the 130 had a gate ... it can be added to the 130

Awesome! Thank you :)
K so weird because I'm certain I have the 130D the manual that came with tank is the 130D and person I purchased from is legit. When I get home I'll look for the "water level window" but shocked I haven't noticed it yet. I don't use the skimmer cup Red Sea said it's not needed. I do have the "gate" though. So on another note the Tunze 9001 skimmer I gave up on yesterday and just turned it off which I don't love not running my skimmer for going on day and a half I'll try it again after work and just let it run. Only way I could get skimmer collection cup to stop filling with water within 3-5 minutes was to turn air intake just about off is that OK to do or should I leave it fully open and just let it do it's thing? Thank you SO much for your help!! :)
