Guys guys guys I bought new stuff for my tanks! The first thing is biological filter media (superfish) then I bought a TDS meter with calibration solution and tested it immediately (after calibrating) turns out: my shrimp tank has a higher ppm than the tank of my brother. It’s not excessively high but it could be better (especially for shrimp).
I also bought a hang on back filter (finally!). Ive been looking for a good one for months now. I found some HOB filters on ebay but decided not to do it since the shipping cost costed more than the actual filter..
I went to a european (BENELUX) website called aquarush it’s pretty good, the prices are decent, the shipping cost too. So here’s my filter! I was supposed to buy those flimsy filter pads that cost an eye but decided to do it my way since I had this new filter media. I used activated carbon (JBL) and fine white filter whool and, as a final touch the new filter media. I must say the new filter is verrrrry quiet!
I also checked my DIY CO2 system since I had some problems earlier (bubbles coming out of the caps, giving too much bubbles,…). The whole thing works! the plants are growing and getting better (I had some problems with algae).
