I am noticing the same thing on my RKL pH probe. I'm about 2 months on a water change myself and it has dipped to the 7.9 area from around 8.2...
Drilled holes and check valves are both a false sense of security and will fail period. The ONLY proven, foolproof method of backflow prevention is...
To make these even better, try a variable voltage power supply to vary the fan speed. In winter months you don't need as much cooling so slowing the...
I use a MJ1200 powerhead with a piece of vinyl tubing stretched over the outlet nipple, works great and most people have one laying around already.
The way the closed loop is presently drawn it shows the suction or intake pulling from the sump, not the display so that would need to be corrected...
Do you have a protein skimmer and did you happen to use tap water or treat the water with chemicals like Prime, Stresscoat or other dechlorinating...
Your closed loop as drawn in aqua color is not a closed loop. It is a return circuit returning water from the sump to the display. A closed loop by...
I leave the back wall and rock alone. My Son painted the back of his tank blue and the corraline on the back looked like heck so he scraped his off...
I leave it on the exterior of the powerheads for a few months until the buildup starts restricting the intake screens. I then soak them in straight...
Purple Up is just ground up calcium. I wouldn't use it myself. You will soon be tired of all the nuisance corraline algae even without the...
I think you are going to have microbubble problems. The purpose of multiple over-under-over type baffles is to make the water follow a specified path...
Are your skimmer and return pump in the same sump section? If so this will be a problem. Microbubbles is the obvious one but the changing water...
I've always used uncured Walt Smith Live Rock myself. I tried dry rock in some of my other systems and it never looked as good as the real live rock...
That is not a good idea. Check valves in saltwater applications are not recommended, it does not have to be a catastrophic failure, even a grain of...
You may not gain anything as far as heat generation. True extrenal pumps are fan cooled and need sufficient room for air flow around the motor for...
Is the sump drilled for the pump intake? Centrifugal aquarium pumps do not suck or lift water and are not self priming so the pump would need to be...
Refurbished 90-GPD RODI System Refurbished 90-GPD RODI System I prefer this meter for $5 more: HM Digital TDS-4TM Pocket Size TDS Meter
Don't let the Refurbished title fool you. Those are brand new systems with all new filters, membranes and DI, they may have a scratch or scuff on a...
The MaxCap is the best RO/Di system on the market today. I am on my third iteration, the first was the 90 GPD, the second was a dual membrane 180 GPD...
Buy the RO/DI directly from Spectrapure for best pricing. There are no other RO vendors that treat and test their RO membranes, use absolute rated...
