OK, the 75gal is gone. I do miss it, but I also like not having to come up with 4' of wall for the thing. I picked up a cheap 29gal set up, upgraded to a 2 bulb fixture and decided to try the low tech plant technique (ie, no CO2, no fertilizer). The first pic is from about week 2.5, the second is week 4ish. Filter is a Penguin 125. Last water test was 0 for nitrite & ammonia, 7.5 nitrate, 7.5 pH. How's it looking?
