Ranco ETC 211000 dual-stage temperature controller. Works perfectly! Wired. $65.
Phosban reactor. It has mesh for biomedia added, but I can take it off if you prefer- it is just on with fishing line. $10. I can throw in a maxijet for $5.
Base rock - That is a 15g sterilite tub. pieces range in size and shape, but are generally M/L. Probably best for a 30-90 gallon tank, imo. $1/lb or $25 for whole tub. It probably weighs about 30-40lbs my guess. I can weight it if you must know before coming.
Dosing pump - works great. It is a peristaltic pump with ability for two channels or one. So, you could dose two-part, or just kalkwasser, or really anything else you want. The tubing I'm including is best for two channels. There is a large range of dose rate, or you can have it dose by volume, etc. $120
Thanks guys! Please support my downsize, I am a terrible pack rat and have gotta make headway on this. Also, I have lots of goodies to throw in for purchases. Plugs, supplements, filter bags, etc. Cheers, Angela
