how much UV wattage you got running on the tank?

i got the motor as slow as a complete revolution every 30 mins. any slower and it kinda freaks out *lol* suppose i could control it w/ the apex, fire up every 4hrs for 30 mins

YAIR (yet another isaac rant) why are algae scrubbers so expensive? 2x LED panels.. $25-50 each small tall acrylic or glass tank... maybe $50 some plumbing... $10? plastic screen... like 10 cents I could see these for like 100-150... but 3-500? come on.

Anyone ever use this? https://www.bulkreefsupply.com/insta-set-super-glue-accelerator-bob-smith-industries.html It warns of heat generation, but does the solution have any adverse affects to certain/all corals? share your wisdom, oh experienced fraggers.

code i have so far... /* Stepper Motor Control - one rev back and forth This program is for the SparkFun Easy motor driver board. This program drives a bipolar stepper motor. The motor is attached to ground plus digital pins 8 and 9 of the Arduino. The motor should revolve one revolution in one direction, then one revolution in the other direction at a speed determined by the milliseconds in the microSecDelay variable.

still tweaking speed/rotation!

so i've decided to try and make a skimmer neck cleaner. what i have so far: stepper motor http://amzn.to/2vU9OjH stepper motor driver http://amzn.to/2vTQraI arduino to control driver http://amzn.to/2vTuKr9 If I can get this combo to go in one revolution every hour or two, the plan is to 3d print a shaft and mount some squeegees on it, the run a belt between the stepper motor and the shaft. I cant mount the motor directly ontop, as i have a clearance issue (ugh). will post picts once i have something!

thats the way to go!

I use these alot: http://ebay.to/2eGXMDw allows me to control crap w/ the varspeed ports. i have a usb fan wired through it... so it only turns on for 15mins every hour...more at night.... jut as an example. cheap/sturdy relay using varports

wall warts

yup.. longer you get, more chance of interference tho. try and keep them away from 120v power cords. just like in home theater world... one side of the cabinet AC, one side DC/video.

those are standard male/male cables. check monoprice/amazon. alternatively, you can get a gender changer and use an old one.

awesome, welcome!

So, i couldnt find any 19v regulated power supplies... but I did find this combo that would work. Math: [email protected] = 89.3watts x4 = 357 ( http://www.rapidtables.com/calc/electric/Amp_to_Watt_Calculator.htm ) Items: 2x http://amzn.com/B019OOTL7A 24vDC 8A (200w) $17.99 4x http://amzn.com/B01H97ETVM 24v to 19v stepdown regulator (95w) $16.99 grand total for all 4: $103.94 Then compare it to just having backup bricks: http://amzn.com/B01KLLSNJ2 $13.66 or $54.64 for 4. so, for high output 19v, its actually better to stick w/ the bricks, since backups are cheap and quick to get. any 90+w 19v laptop power supply will work! hell, discount electronics! maybe your power supply holding box just needs a fan or two?

I'd recommend upgrading your power supplies. these "bricks" are prone to overheating, and are overpriced. look for something like this: http://amzn.to/2eE8Dht they come in differing voltages and wattage ratings. I run 5 AI Sol's w/ one of these, and cheap enough to have a spare just sitting there waiting. The original sol bricks got so hot they started melting, if they didnt just quit first.

im at about 2gal/day on a 180DT w/ a 20frag, and 30g fuge and 50g (well, 30g whane running) sump. sump is also in the garage.

not sure what caused it, and i cant pull out the healthy ones today to frag them off. (r22 AND anti-freeze on my hands earlier) bleh

ugh, woke up to this... Sent from my SM-G920P using Tapatalk

now thats what i call a massive heavy jig.

my biocube's dinos finally went away after adding more fish and feeding more. i think the trick is to out-compete the crap. what crap? now, its obviously not a cure-all, because just peroxide alone didnt help me.

have you re-tried peroxide while having elevated nitrate/phosphates?

i had that problem last year, when i refilled my media, i upped the ratio. 3 scoops coarse arm, one scoop neomag. This ratio is well above what the bag says, but its seems to be perfect since. you can see layers in my reactor since i didnt really mix it in,

hell, the taps are the easy part

A new army has joined the war against the axis of palys... I was able to remove 4 old old plugs which had paly overgrowth. 2 went to the trash (they just didnt look nice), two are going a the sale thread! check out the GSP snuffing out that one paly on the right.

moody gardens aquarium has a window into the back room. that skimmer is easily 4ft wide and 12-16ft tall. i gotta find a pict. i know i have it *lol*
