| The microstrainer would work better for sure. However, due to cost, I suggested the Matala. You could always start there and see how it works out. If not, it gives you the time to be able to save a few bucks and then invest in the microstrainer.
What about your pump situation? Are you up for fixing that issue? Two for the price of one and you'll actually increase for flow rates! Something to think about, eh?
Incidentally, as far as the BD is concerned, are you saying that the entire dome screws off the Rhino and the Koi Toilet doesn't? The first part is true, but the air diffuser IS the dome. That's why it's so much more to replace it when necessary. The koi toilet's dome also screws onto the support post and includes an o-ring to prevent air from escaping once threaded on. The air diffuser then threads onto the dome and they are separate pieces. Thus the greater savings when replaced. But, it's up to you. I have installed the Koi Toilets on three jobs now and they really work out beautifully. Also, when used in a gunite pond, they are "code" where the Rhino is not!
