I have a biocube 14 and I would imagine that you have the same 3 chambers in the back.....I run in the middle chamber with an In Tank media basket, floss on the top, chemipure elite and I have chaeto in the bottom which really helps with the nitrates. You may be over feeding or have too heavy a bio load. How many fish and how often do you feed? My phosphates dropped dramatically when I cut down on feeding as well as put in the chaeto.
I've got intank media basket as well, run floss, carbon and chem pure elite.
Tried chaeto in the back with intank underwater fuge light on reverse cycle but my temps were getting too high. Even now I struggle to keep it below 84 (which I know is high).
have 2 fish (small clarki clown and yellow tail damsel) and a peppermint shrimp along with a small cuc.
Used to feel daily but have cut that back to every other day
I struggle with the temp issue as well. I find that if I leave the small feeder lid open half way I can get my temp below 84. It sounds like you're doing all the right things...any chance the meter is not properly callibrated?
If you have algae and are testing at .18, odds are your phosphates are much higher. The temp, flow, lighting bio load and feeding should all be checked. Increase flow, try and bring that temp closer to 80, how many fish in an 8 gallon? one or two? Feed once every other day, half of what your feeding now. Make sure your RO unit is not pumping phosphates in, ive had that happen.
tested again last night and got .23, did not get a chance to test my ro/di water...will do that tonight.
I know for a fact my temps are on high side from 81 to 84.
with lighting I assume I might be running my lights too long?
Flow is a korilia nano, the hydor thing on the pump return does not turn anymore.
Have started feeding every other day.
Picke dup a used RSM130 that I'll move to but till that's setup want to keep this going and healthy and of course learn what I am doing wrong and not repeat it in the bigger setup.
