dragon79 Posted February 23, 2005 Share Posted February 23, 2005 I always found to break that surface scum was to point that nozzle straight up. It breaks the water and it still adds flow. Would be nice to point it in a different location and have that tape skim for me though. I'll have to try it on the jbj. Now to find a pesky black tape cover or any cover for that matter, lol Link to comment
NanoNoob Posted February 23, 2005 Share Posted February 23, 2005 The suction will hold these things in place but you still get water sucked in around the edge. Not a big deal really except it will suck in food. Again not a big deals really. I epoxied my version and it works much better with a complete seal around the edges. Who said there would be no more uses for those tapes????? Link to comment
dga Posted February 23, 2005 Share Posted February 23, 2005 ive got tons of old cassettes. only $29.95 ea. can't have my boy george one though. Link to comment
ccjung Posted February 23, 2005 Share Posted February 23, 2005 dga, you got PM. Lets talk about the ripoff I MEAN sale of these SUPER SKIMMERS !@!@! Ok you dont really have PM and this is the coolest DIY mod by far. The award goes to Doriftu for sure! Doriftu, would you honor me by posting this DIY on my site? www.nanocustoms.com/catalog/user_support.php My site is down right now but will be up later. Thanks Chris Link to comment
jmt Posted February 23, 2005 Share Posted February 23, 2005 Chris: have you ever thought of hosting a nano cube forum on your site. To be honest, I get kinda of annoyed when I have to sift through the 20 new nano cube threads a day. Also, I came across a place that sells cheap tapes with the black case. If anyone is interested, I'd be willing to buy some and ship them out (tape included). It wouldn't cost too much. Link to comment
dcabboa Posted February 23, 2005 Share Posted February 23, 2005 I have another suggestion - use one of those double cases and put some chaeto in it. Nano fuge! Link to comment
embryoguy Posted February 24, 2005 Share Posted February 24, 2005 i just set it up! it works great on my deluxe 12g. but i cant seem to get it to work on the 12 original nanocube. has anyone tried it yet? thanks Link to comment
Nickeleye Posted February 25, 2005 Share Posted February 25, 2005 Well, that takes the cake. Wish I thought of that before I spent $10 in parts and a couple hours putting together my own box. Does the cassette case create any extra noise due to the water falling? I had to add a couple sponges to my setup to keep the falling water from making a lot of noise. Link to comment
barbadeau Posted February 25, 2005 Share Posted February 25, 2005 the old school cassette tapes had BLACK backs, that would be even better jah? I'll have to look mmmmkay Link to comment
Doriftu Posted February 25, 2005 Author Share Posted February 25, 2005 ya, we are all trying to find the black ones, however, the more i think about it, the more i like the clear one, as its much easier to see if it needs to be raised or lowered without having to pop open the hood, not that we all dont do that on a daily basis anyway. I think i will still probably change it out for a black one Link to comment
Perpetual98 Posted February 25, 2005 Share Posted February 25, 2005 What is this thing you refer to as a "cassette"? Link to comment
jcm1229 Posted February 25, 2005 Share Posted February 25, 2005 The clear ones will also let you visually check to make sure the "grate"isn't in danger of being blocked for any reason. Link to comment
hngu7721 Posted February 25, 2005 Share Posted February 25, 2005 i'm having a problem with restrictin water entry into the grate. There is no differential in water level on either side of the casette case There doesn't seem to be the waterfall effect akin to an overflow with my setup. Am i doing something wrong? Any suggestions? Thanks Link to comment
dms12 Posted February 26, 2005 Share Posted February 26, 2005 wow.. this worked great.. :-) Link to comment
dms12 Posted February 26, 2005 Share Posted February 26, 2005 a lil less water in the tank. till it drips over Link to comment

Any suggestions? Thanks You might not have a strong enough pump. i use 2 - hagen 301's which are around 170gph rating and really makes the water "niagra falls" over the skimmer. Link to comment
dga Posted February 26, 2005 Share Posted February 26, 2005 Based on "doriftu's" idea, a slight mod can make the cassette cover moveable and not fall off when pumps are turned off. i found a cover that had hole indents that keeps the tape taught instead of the cross pattern ones. inserted a small rubber piece of tubing. into that is 2 plastic screws that fit tightly through the intake slots of the back wall. just line the two up and this great idea from "doriftu" can be adjusted up and down without moving to easily. its basically a press fit. this idea is really great as it can adjust how much water is in the sump area, and as the last pic shows allows my upper powerhead to be more than half out of the water thereby reducing water temps. Cant get a thumbnail image to post from the site i found. these pics are allready resized down by 35 percent. More turbulance Slide it up for less turbulance Link to comment
xtm Posted February 26, 2005 Share Posted February 26, 2005 Can I chip in-- this was my experience with these mods---I did the exact same mod and I learned a LOT about what works and what doesn't (see the other thread in the DIY forum) This cassette "mod" will look like it's working, but wait a few more days-- the area inside the cassette tape will get filled with surface scum and it will halt the surface skimming process throughout the tank---- the collected surface scum will stay inside that cassette tape area and continue to accumulate until you remove the "mod" and clean it up. The surface scum will not move "inwards" because the grills of the nanocube inlet is preventing it to "go through". Only the water underneath the scum is allowed to flow, leaving the surface scum to accumulate on the top. The only EFFECTIVE way to move the surface scum through the inlet is to remove the inlet grills- which brings us to the next problem-- ONLY the water below the scum is filtered by the sponges, the surface scum is still left to accumulate on the top! (go figure) In my setup, this is how I eliminated the surface scum: I completely removed the grill to allow the surface scum to pass through ( Fig A ) Since I don't use sponges/foam for mechanical filtration, I drilled a hole ( Fig B ) for the scum to finally drop into the sump ( Fig C ) This way, even the surface scum moves OUT of the nanocube, not just the water underneath.

superman Posted February 26, 2005 Share Posted February 26, 2005 that sounds like a good idea. Link to comment
Nickeleye Posted February 28, 2005 Share Posted February 28, 2005 And for those without an acutal sump? hehe I have switched to this mod as of today from my other very similar mod because my DIY mod ended up being very noisy (not to mention annoying when you're trying to sleep). I guess I'll wait and see how it works. My other one (although noisy) didn't show any signs of the surface scum building up within the box. Maybe I just have less surface scum... who knows.
