Thank you so much! This is all fabulous information. I picked up two AquaClear 70's in Amazon's awesome sale, so I'm thinking to grab another for the 10g. Is the AquaClear 30 a good size for the shrimp in this tank size? This may be a silly question, but do they have just a sponge 'sock' that fits right over the intake or do you have to retrofit it yourself? I have seen the sponge filters that require airline tubing and whatnot, but I'd prefer to utilize the standard filter.
Also, I have never used a sand substrate. If I go this route and plant with moss, java ferns, anuabis and floating plants, what kind of ferts do I need? Root tabs and liquid fert? Also, I have seen a liquid CO2...does this work? Or should I be looking into CO2? Also, how do you clean sand with a gravel vac?
Thank you all so much for your info!
