your nitrate drop so fast might cuz of your 4" DSB
, it take time for the DSB
to start working, but anyway, now u get everything under control ^^
once thing about the cleaning crews, you don't really need that much, as someone in here told me. I was gonna gonna a 50gal package from them too.
I would suggest pick couple that u like and get your order up to $99 and get free shipping. also order over $75 u can have a small cleaning crew from them, so why not get some feather duster or corals instead of big bags of snails and hermits. JMO, get nass snails if u want sand bed stirrers, they r omg fast!!!
here is a cheaper website for basic cleaning crews and macro algae
I can't tell you how well their nerite snails help cleaning the diatom problem, its just amazing LOL. and OMG its much cheaper!! Priority Mail is a flat rate of $7.50~
and the owner(I think), he is so cool, he will throw extra snails in the bag.
I ordered 15 nerites+25nass+5mangroves first time, he gave me 18 nerites, 29nass and 9mangroves. highly recommend!
oh btw~ thats a big star right there hahaha
