One major issue that has come up with the PWC units is leaks. Many people have good luck with them (no leaks) but some people have bad leaks with them where they simply have to re-tape all the joints to seal the leaks. Other than that, they are good units. If you are going to do drinking water, the one with the tank is a good choice. Just remember that a 100gpd unit only rejects 90% of TDS through the RO membrane and the remaining 10% is left to the DI cartridge. If you get a 75gpd or a 150gpd unit, the rejection rate is 98% so that the DI lasts longer. The only difference in the 75, 100 and 150 gpd units are the RO membranes and the Flow Restrictor. You can run one as a 100gpd unit and when its time to replace the RO membrane, get a new Flow Restrictor and RO membrane and bump it up to a 150gpd unit.

How do plan to cycle the tank? Well you probably feel that you are going through your cycle already based on you current readings but I would recomend dropping a coctail shrimp in the system to create a hard cycle, very large ammonia spike. When the #'s zero out again then you are ready for your cleanup crew.

1. Get my temperature stable. I installed the optional water cooling fan this afternoon and now I'm trying to dial in my thermostat.
2. Figure out my RO/DI purchase. I want to have a RO/DI with a DI Bypass into a pressurized drinking water tank. Maybe I'll be able to talk with "The Filter Guys" or "Air Water & Ice" on Monday and make a decision between them. The price savings from PWC is attractive but the hit or miss issues with leaks has me leery of that solution.
3. Determine if I can trust my API and Jungle Test Strips for water testing. If I can't then maybe something like SeaChem would work better. Daily testing is in order until I figure things out. :yes:
4. Get my Cycle started. I have Bio-Spira (live nitrifying bacteria) that should fill in the gaps for good bacteria that I might be missing from my live rock and live sand. I'm supposed to turn off my protein skimmer for 48 hours before I add the Bio-Spira so I should be able to add it tomorrow night before I hit the sack. After I add the Bio-Spira I'll be more comfortable doing something drastic like adding a dead shrimp.
About that idea, are you guys just messing around or is that really a good idea to "shock" my tank with something toxic like a dead shrimp? If it's a good idea, how long do I leave that stinky thing in my tank? :yikes:
no need. the minute amount of tap water present after sqeezing out the sponge really well won't hurt anything.Vox;344730 wrote: I just changed my mechanical filter, this black spongy thing that sits down near the intake of my protein skimmer. I rinsed it with unfiltered tap water first, sqeezed out the water, gave it another rinse with RO/DI water, sqeezed out the water, and reinserted.
Should I only use RO/DI water to rinse out the filter?
Add "buy a refractometer" to your list.
I simply took a 15 gallon drum and fill it with RO water. It was designed to sit on the counter with a faucet in the lid. It laid on its side and water gravity drained out.
